Question

Laura baked a cake. She gave 1/5 of the cake to Alex, 1/3 of the cake to Erikson, and 1/10 of the cake to Auturn.

How much is left for herself?

Answer 1

11 pieces

Explanation:

So you take all the fractions and find the LCM which would be 30

1 / 5 and multiply the numerator and the denominator by 6 = 6 /30

1 / 3 and multiply the numerator and the denominator by 10 = 10 / 30

1 / 10 and multiply the numerator and the denominator by 3 = 3 / 30

then you add up the numerators which would be 19 and then you would do 3- pieces subtracted by 19 which is 11 pieces
