Question

Beth needs 1 2/3 cups of sugar to make a cake and 2 1/4 cups to make a pie. How much sugar does she need to make both?

Answer 1

you are adding
1 2/3 + 2 1/4

first these are mixed fractions lets change them to regular fractions
for 1 2/3 take the whole number and multiply by the denominator 3 and add the numerator, then that number over denominator 3 so

1 x 3) +2 = 5/3

do that with 2 1/4

what did you get?
