Question

Angel has two baby guinea pigs, Whiskers and Scamp. The sum of their weights is 1 7/8 pounds Whiskers weighs 3/8 pound less than Scamp. How much does each guinea big weigh?

Answer 1

`(9)/(8) [W]\ and \ (3)/(4) [S].`

Explanation:

1. if the weight of Whisters is 'w', then the weight of Scamp is 'w-3/8'; then

2. it is possible to make up the equation:

`w+w-(3)/(8)=1(7)/(8);`

3. if to solve this equation, then w=9/8 - this is the weight of Whiskers;

the weight of Scamp is 9/8-3/8=6/8=3/4 [pounds].
