Unlike denominators and Unlike numerators

Compare Fractions with like Denominators

• Are the denominators the same?

• Which fraction has more pieces colored (numerator)?

• If the denominators are =, the fraction with the LARGER numerator is the LARGER fraction.

After we multiply the numerator and the denominator of 5/6 by 2, what will the new fraction be?

Multiple Choice

Let's compare the fractions now:

Is 10/12 greater than, less than, or equal to 4/12?

Let's Review!

• We noticed the denominators were different.

• We figured out that it would take two sixes to make 12.

• When we multiplied the numerator and denominator by 2, we created fractions with like denominators.

• We found that 5/6 is much LARGER than 4/12.

• YES

• NO

Let's Review!

• We noticed the denominators were different.

• We figured out that it would take three fours to make 12.

• When we multiplied the numerator and denominator by 3, we created fractions with like denominators.

• We found that 3/4 is much LARGER than 4/12.

Multiple Choice

Let's compare the fractions now:

Is the new fraction, 6/8, greater than, less than, or equal to 1/8?

• >

• =

Let's Review!

• We noticed the denominators were different.

• We figured out that it would take two fours to make 8.

• When we multiplied the numerator and denominator by 2, we created fractions with like denominators. And 6/8 is greater than 1/8.

• So, we found that 3/4 is LARGER than 1/8.
