I can not understand this please can you help

Answer»

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{<klux>2</klux>}{3}

= 2:3

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

Answer: 2 : 3

I hope this HELPS. :D
