Addy has mowed 1/6 of the yard. Brin says that Addy has mowed 3/7 of the yard. Is Brin correct? Explain.

• Brin is correct because 1/6 and 3/7 are both less than 1/2 ; therefore, 1/6 and 3/7 are equivalent fractions. 

• Brin is incorrect because equivalent fractions are found by multiplying by a fraction equal to 1, not by adding a fraction equal to 1. 1/6 X 1/1 does not equal 3/7; therefore, 1/6 and 3/7 are not equivalent fractions.

• Brin is correct because 1/6 + 1/1 = 3/7 ; therefore, 1/6 and 3/7 are equivalent fractions. 

• Brin is incorrect because 1/6 and 3/7 have different denominators; therefore, 1/6 and 3/7 are not equivalent fractions.

Carlota has ran 1/4 of the field. Airi says that Carlota has ran 2/8 of the field Is Airi correct? Explain.

• Airi is correct because 1/4 and 2/8 are both less than 1/2 ; therefore, 1/4 and 2/8 are equivalent fractions. 

• Airi is incorrect because equivalent fractions are found by multiplying by a fraction equal to 1, not by adding a fraction equal to 1. 1/4 X 1/1 does not equal 2/8; therefore, 1/4 and 2/8 are not equivalent fractions.

• Airi is correct because 1/4 X 2/2 = 2/8 ; therefore, 1/6 and 2/8 are equivalent fractions. 

• Airi is incorrect because 1/4 and 2/8 have different denominators; therefore, 1/4 and 2/8 are not equivalent fractions.

Bentley has swam 1/5 of the pool. Ethan says that Bentley has swam 2/9 of the pool. Is Ethan correct? Explain.

• Ethan is correct because 1/5 and 2/9 are both less than 1/2 ; therefore, 1/5 and 2/9 are equivalent fractions. 

• Ethan is incorrect because equivalent fractions are found by multiplying by a fraction equal to 1, not by adding a fraction equal to 1. 1/5 X 2/2 does not equal 2/9; therefore, 1/5 and 2/9 are not equivalent fractions.

• Ethan is correct because 1/5 + 2/2 = 2/9 ; therefore, 1/5 and 2/9 are equivalent fractions. 

• Ethan is incorrect because 1/5 and 2/9 have different denominators; therefore, 1/5 and 2/9 are not equivalent fractions.
