Joey has mowed 1/4 of the yard. Mark says that Joey has mowed 3/6 of the yard. Is Mark correct? Explain.

• Yes. Mark is correct because 1/4 and 3/6 are equivalent fractions. When you add 2 to 1/4, it equals 3/6.

• No. Mark is incorrect because 1/4 and 3/6 are not equivalent fractions. When you multiply the numerator and denominator of 1/4 by 3, you get 3/12, not 3/6.

Mackenzie and Alma ordered the same sized sandwiches for lunch. Mackenzie had 1/6 of a sandwich, and Alma had 3/4 of a sub. Who ate more? Explain.

• Since 1/6 < 3/4, Alma ate more.

• Since 1/6 > 3/4, Mackenzie ate more.

• Since 1/6 = 3/4, they both ate the same amount.

• The two subs are different sizes, so we can't compare them.
