Mrs. lapp gives each of 6 children 1/8 of a cake. how much of the cake does she give them in all?

When you add fractions the denominators have to be the same, in this problem, this is the case. the numerators, or the top numbers will add, but the denominators, or the bottom numbers, will stay the same. so if you add

1/8 + 1/8

it would be 2/8

so if you add all 6,

1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8

you would get 6/8

or if you have to simplify, divide both top and bottom numbers by a common number they share, in this case this number is 2.

after dividing you would get your final answer of 3/4
