Question

I can not understand this please can you help

Answer 1

Explanation:

Let b's weight be x. Then a's weight is 2x/3.

A ratio can also be expressed as a fraction, so a/b

$= \frac{ \frac{2x}{3} }{x}$

$= \frac{2x}{3} \div x$

$= \frac{2x}{3} \times \frac{1}{x}$

$= \frac{2}{3}$

$= 2:3$

Hence, the ratio between the weights of a and b are 2 : 3.

Answer: 2 : 3

I hope this helps. :D
