Question

What is the weight of one half of two thirds of a sack of rice? The sack of rice weighs 99 kilograms.

Answer 1

First you need to find what 2/3 equals
to do this, take 99 divided by 3
99/3=33

if 1/3 equals 33, two thirds would be 33x2
33x2=66

now, you need to find 1/2 of 66.  this can be done 2 different ways

1.    66 divided by 2    -    66/2=33
OR
2.    66 x 1/2 = 33     OR     66 x .5 = 33

The answer is 33 kilograms

Answer 2

The weight of the sack is 2/3 x 99 weight = 66 1/2 x 66= 33 kilograms hope this helps
