Question

Janis is at the store shopping for snacks for her trip to the zoo. She purchases 9 / 11 pound of grapes, 1 3/4 pounds of bananas and 2 5/6 pounds of apples.
(A) what is the weight of each type of fruit in decimal form?
(B) Does the weight of each type of fruit in decimal form represent a rational number? Explain.

Answer 1

Answer:

A. What is the weight of each type of fruit in decimal form?

Grapes in decimal form = 0.8181 pounds

Bananas in decimal form = 1.75 pounds

Apples in decimal form = 2.8333 pounds

B. Does the weight of each type of fruit in decimal form represent a rational number? Explain.

Of course, each of the weights of the fruits in decimal form represent a rational number. The weights can be expressed as a fraction where both the numerator and the denominator in the fraction are integers, like we checked with 9/11, 1 3/4 and 2 5/6. The denominator in a rational number cannot be zero.
