Question

Lisa and Ann are eating a box of crackers. Lisa eats 3/6 of the box,and Ann eats 1/4 of the box.How much of the box did the two girls eat together?

Answer 1

Lisa and Ann ate 3/4 of the box together

Solution:

Given that,

Lisa and Ann are eating a box of crackers

$Lisa\ ate = \frac{3}{6}\\\\Ann\ ate = \frac{1}{4}$

How much of the box did the two girls eat together?

$Together\ eaten = Lisa\ ate + Ann\ ate\\\\Together\ eaten = \frac{3}{6} + \frac{1}{4}\\\\Together\ eaten = \frac{1}{2} + \frac{1}{4}\\\\Together\ eaten = \frac{1 \times 2}{2 \times 2} + \frac{1}{4}\\\\Together\ eaten = \frac{2}{4} + \frac{1}{4}\\\\Together\ eaten = \frac{3}{4}$

Thus Lisa and Ann ate 3/4 of the box together
