Question

Cora is making cake. She needs 1/2 cup butter for thr cake and 1/4 cup butter for the frosting. How much butter does she need altogether

Answer 1

`(3)/(4)`

Explanation:

we add the 2 fractions together

`(1)/(2) +(1)/(4)`

To add we convert the denominator to make them equal and we can convert first one to 4 by multiplying the numerator and denominator by 2

`(1*2)/(2*2) +(1)/(4) \\\\(2)/(4) +(1)/(4)`

Now we just add the numerators and keep the denominators the same

`(2+1)/(4) \\(3)/(4)`
