Answer 2

Given:

Rohan had 36 pens.

He gave 15 to Mike.

He gave 11 to Karen.

To Find:

The fraction of the pens Rohan left.

Write two equivalent fractions for that amount

Explanation:

Equivalent fractions are fractions written in different forms but simplify to be the same fraction. We can find equivalent fractions by multiplying or dividing  both the numerator and the denominator by the same number.

Solution:

Find the pens left;

Pens left = 36 - 15 - 11

Pens left = 10

Find the fraction of the pen left:

$\text{Pen left} = \dfrac{\text{Pens Left}}{\text{Total number of pens}}$

$\text{Pen left} = \dfrac{\text{10}}{\text{36}}$

Write two equivalent fractions:

$\dfrac{10}{36} = \dfrac{10 \div 2}{36 \div 2}$

$\dfrac{10}{36} = \dfrac{5}{18}$

$\dfrac{5}{18} = \dfrac{5 \times 3}{18 \times 3}$

$\dfrac{5}{18} = \dfrac{15}{54}$

Answer: There are 10/36 pens left. The two equivalent fractions are 5/18 and 15/54
