Select the statement that this model represents

​a. 6/6 = 6/12

b. 5/6 = 6/12

c. 5/6 = 10/12

d. 6/5 = 10/12

Multiple Choice

Select the statement that this model represents

• $$\frac{4}{12\ }=\ \frac{8}{12}$$

• $$\frac{4}{6}=\frac{8}{12}$$

• $$\frac{6}{4}=\frac{8}{12}$$

• $$\frac{6}{6}=\frac{8}{10}$$

Liz has eaten 2/3 of the brownie pan. Julie says that Liz has eaten 3/4 of the pan. Is Liz correct? Explain.

a. Liz is correct because 2/3 + 1/1 = 3/4; therefore, 2/3 and 3/4 are equivalent fractions. 

b.Liz is correct because 2/3 and 3/4 are both less than 1/2 ; therefore, 2/3 and 3/4 are equivalent fractions. 

c. Liz is incorrect because equivalent fractions are found by multiplying by a fraction equal to 1, not by adding a fraction equal to 1. 2/3 X 1/1 does not equal 3/4; therefore, 2/3 and 3/4 are not equivalent fractions.

d. Liz is incorrect because 2/3 and 3/4 have different denominators; therefore, 2/3 and 3/4 are not equivalent fractions.

Multiple Choice

Cole has cleaned 1/5 of the room. Casey says that Cole has cleaned 2/6 of the room. Is Casey correct? Explain.

• Casey is incorrect because 1/5 and 2/6 have different denominators; therefore, 1/4 and 2/6 are not equivalent fractions. 

• Casey is correct because 1/5 + 1/1 = 2/6 ; therefore, 1/5 and 2/6 are equivalent fractions. 

• Casey is correct because 1/5 and 2/6 are both less than 1/2 ; therefore, 1/5 and 2/6 are equivalent fractions

• Casey 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 1/1 does not equal 2/6; therefore, 1/5 and 2/6 are not equivalent fractions.
