Ruby ate 1/5 of a pie . If there was 10 slices of pie , how many did she eat . <br> SHOW YOUR WORK
Ksju [112]

Ruby eats two slices of pie

Fraction generally represents a part of the whole. The number present in the upper side is called as numerator and the number present below is called as denominator. Fraction can also be represented as a decimal or percentage when required.

Fraction of pie Ruby ate = 1/5

Number of slices present in the pie = 10

numerical value of a fraction = fraction x total number

So, total number of slices of pie that Ruby ate = 10 x 1/5 = 2

Therefore, Ruby eats two slices of pie.

Ruby ate 1/5 of a pie and if there was 10 slices of pie, it implies Ruby eats two slices of pie.
