Answer 2

Answer:

Junior is 1.8 m tall.

Step-by-step explanation:

Given, Junior's brother is $1 \frac{1}{2} \: m$ tall.

So, height of Junior's brother $= 1 \frac{1}{2} \: m = \frac{3}{2} \: m$

It is also given Junior is $1 \frac{1}{5} = \frac{1 \times 5 + 1}{5} = \frac{6}{5}$

of his brother's height.

So, Height of Junior $= \frac{6}{5} \times \frac{3}{2}$

We know,

$\frac{z}{x} \times y = \frac{z \times y}{x}$

By some examples, we can understand this concept more easily$\frac{1}{2} \times 10 = 5$

Example-2:

$\frac{2}{3} \times \frac{5}{2} = \frac{5}{3}$

Example-3:

$\frac{5}{2} \times 100 \\ = 5 \times 50 \\ = 250$

Now, Height of Junior

$= \frac{6}{5} \times \frac{3}{2} \\ = \frac{3 \times 3}{5} \\ = \frac{9}{5} \\ = 1.8 \: m$

This is a problem of fraction.
