Front

What does the numerator in a fraction represent?

Back

The numerator represents the number of parts we have.

Front

What does the denominator in a fraction represent?

Back

The denominator represents the total number of equal parts the whole is divided into.

Front

How do you add fractions with the same denominator?

Back

Add the numerators and keep the denominator the same. For example, 1/4 + 2/4 = (1+2)/4 = 3/4.

Front

How do you subtract fractions with the same denominator?

Back

Subtract the numerators and keep the denominator the same. For example, 3/5 - 1/5 = (3-1)/5 = 2/5.

Front

What is the process to multiply fractions?

Back

Multiply the numerators together and the denominators together. For example, (2/3) * (3/4) = (2*3)/(3*4) = 6/12 = 1/2.

Front

What is the process to divide fractions?

Back

Multiply by the reciprocal of the second fraction. For example, (1/2) ÷ (3/4) = (1/2) * (4/3) = 4/6 = 2/3.
