In real life, we need to do calculations quite frequently.

In our daily life, there are countless examples of arithmetic problems as to calculate the daily expenditure, to find increment and decrement in temperature etc.

So, in order to solve real life problems, we need to identify what kind of operations are to be performed.

In order to figure out, which operation is to be applied in a given word problem, following logics can be used.

**Addition :**If the values of more than one units are given and the problem asks to determine the total units, then addition is used to calculate the total units.**Subtraction :**If the values of two or more units are given and problem asks for the difference of units, then subtraction is used to calculate the difference.**Multiplication :**If the value of a single unit is given and the problem asks for the values of more than one units, then multiplication is used.**Division :**If the values of more than one units are given and the problem asks for the value of a single (each) unit, then division is to be performed.

**For example :** Four girls went to a restaurant and spent $\(50.50\) in total. They split the bill evenly among them selves. How much did each girl pay?

Number of girls = \(4\)

Total amount spent on dinner = $\(50.50\)

To calculate how much did each girl pay, we will divide \(50.50\) by \(4\).

\(50.50÷4=12.625\)

Hence, each girl pays $\(12.625\)

A $\(49.5\)

B $\(14.25\)

C $\(2.25\)

D $\(10\)

In our daily life, there are countless examples of arithmetic problems as to calculate the daily expenditure, to find increment and decrement in temperature etc.

So, in order to solve real life problems, we need to identify what kind of operations are to be performed.

**For example: **Alex buys a DVD player for \($49.95\) and a DVD holder for \($19.95\). If he pays \($100\), how much money does he get back?

Cost of a DVD player = \($49.95\)

Cost of a DVD holder = \($19.95\)

To calculate the total cost of the items, we will add the costs of both the items.

\(\Rightarrow \;49.95+19.95=$69.9\)

To calculate the amount he gets back, we will subtract the total cost of items from the amount he paid.

\(\Rightarrow \$100-$69.9=$30.1\)

Thus, Alex gets \($30.1\) back.

A 1.1 Pounds

B 0.5 Pounds

C 0.4 Pounds

D 0.1 Pounds

In our daily life, there are countless examples of arithmetic problems as to calculate the daily expenditure, to find increment and decrement in temperature etc.

So, in order to solve real life problems, we need to identify what kind of operations are to be performed.

**For example :**

Daniel wants to buy some posters which cost \($9.99\) each but are offered on sale at \($2.35\) less. If he buys \(5\) posters, how much he spends?

To calculate the sale price of one poster, we will subtract \($2.35\) from \($9.99\),

\(9.99-2.35=7.64\)

Sale price of one poster is \($7.64\)

To calculate the cost of \(5\) posters, we will multiply \(7.64\) by \(5\),

\(7.64×5=38.2\)

Thus, Daniel spends \($38.2\)

In real life, we need to do calculations quite frequently.

**For ****example :**

Ms. Wendy made \($30.25\) in the first week and \($41.65\) in the second week by snow shoveling. She decided to divide the total amount equally among her two little sisters. How much amount did each sister get?

To calculate the total amount made by Ms. Wendy, we will add \($30.25\) and \($41.65\),

\(30.25+41.65=71.90\)

Ms. Wendy divided \($71.90\) equally among her two sisters.

To calculate, how much money each sister got, we will divide \(71.90\) by \(2\).

\(71.90÷2=35.95\)

Hence, each sister got \($35.95\)

A \(0.5\,\ell\)

B \(0.25\,\ell\)

C \(10\,\ell\)

D \(1.5\,\ell\)

In real life, we need to do calculations quite frequently.

**For example :**

In Cooper's shopping cart, he has \(3\) pounds of oranges at \($0.95\) per pound, \(4\) cans of soup at \($1.21\) per can, and \(2\) cups of ice cream at \($1.1\) per cup. What is the total cost of the items in his shopping cart?

To calculate the total cost of each item, we multiply the number of items by the cost of each item.

Total cost of 3 pounds of oranges:

\(3×0.95=$2.85\)

Total cost of 4 cans of soup:

\(4×1.21=$4.84\)

Total cost of 2 cups of ice cream:

\(2×1.1=$2.2\)

To calculate the total cost of all items in his shopping cart, we will add the total cost of the three items.

\(\Rightarrow2.85+4.84+2.2=$9.89\)

So, Cooper has items worth \($9.89\) in his shopping cart.

A \($4.25\)

B \($10\)

C \($36\)

D \($12.25\)

In real life, we need to do calculations quite frequently.

**For example:**

Emma sold \(5\) hats at \($22.8\) each. She used all the money to buy \(8\) pairs of socks. What was the price of each pair of socks?

To calculate the total cost of \(5\) hats, we will multiply \($22.8\) by \(5\),

\($22.8×5=114\)

She sold \(5\) hats for \($114\).

To calculate the price of each pair of socks, we will divide \(114\) by \(8\),

\(114÷8=14.25\)

Thus, cost of each pair of socks was \($14.25\)

A \(1.92\) hours

B \(2.32\) hours

C \(4\) hours

D \(1\) hour

In real life, we need to do calculations quite frequently.

**For example :**

Kelly spent a total of \($15.00\) on an evening, of which \($9.8\) were spent on movie show tickets and with the rest amount she bought \(2\) drinks. If each drink had the same cost, how much did each drink cost?

To calculate the total amount spent on drinks, we will subtract \(9.8\) from \(15.00\),

\(15.00-9.80=5.20\)

So, she spent \($5.20\) on 2 drinks.

To calculate the cost of each drink, we will divide \(5.2\) by \(2\),

\(5.2÷2=2.6\)

Thus, each drink costs \($2.6\)

A \(1.0\,\pi\,cm^2\)

B \(1.2\,\pi\,cm^2\)

C \(0.6\,\pi\,cm^2\)

D \(1.5\,\pi\,cm^2\)
