Mrs. Soriano will show you
compare using <, >, =
2/5 to 7/5
They have the same denominator so
2/5 < 7/5
Bella ate 4/7 of a pie. Edward ate 2/7 of the same size pie. Who ate more pie?
Bella ate more because they share the same denominator. When 2 fractions share the same denominator, the bigger numerate is more.
Order these fractions from least to greatest
7/4 7/10 7/8
They have the same numerators. When fractions share the same numerator the smaller denominator is bigger.
7/10 7/8 7/4
Write an equivalent fraction for 2/3
4/6, 6/9, 8/12 and so on
Is 3/4 = 9/12
Yes you can multiply by the whole 3/3
compare using <, >, =
3/4 and 3/ 10
They have the same numerator
3/4 > 3/10
Marnie has 5/8 of candy bar. Luke has 5/10 of the same size candy bar. Who has more?
Marnie has more because they share the same numerators. When fractions share the same numerators, the small denominator wins.
Order the fractions from least to greatest
7/8 1/4 1/2
Compare the fractions to the benchmark fraction 1/2
1/4 1/2 7/8
Write 2 equivalent fractions for 4/6
Draw pictures or multiply by a whole
8/12, 12/18, 16/24 and so on
Is 5/6 = 15/24
No you do not multiply the numerator and the denominator by the same number.
compare using <, >, =
6/10 and 1/2
Half of 10 is 5
6/10 > 1/2
Charlie gave away 3/8 of his goldfish. Charlie says 3/8 is greater than half. Is Charlie correct?
Charlie is incorrect because half of 8 is 4. 3 is less than 4, so 3/8 is less than half.
Order the fractions from least to greatest
7/8 3/6 2/10
Find the fraction that is equivalent to 1/2. Then compare the other fractions to 1/2
2/10 3/6 7/8
Draw pictures or multiply by a whole
8/10, 12/15, 16/20 and so on
Is 4/5 = 8/15
No you do not multiply the numerator and denominator by the same number so they are not equal.
compare using <, >, =
6/8 and 5/9
Cross multiply
6/8 > 5/9
Harry painted 3/5 of his pumpkin. Ron painted 5/6 of the same size pumpkin. Who painted more of their pumpkin?

Mrs. Larson ran 2/7 around a lake. Mrs. Soriano ran 3/10 of a different sized lake. Mrs. Larson says she ran more because she cross multiplied. Why is she in correct?
We cannot compare fractions that are not the same size. The lakes are not the same size so we cannot compare them.
