Question

Which shows how the distributive property can be used to evaluate 7 times 8 and four-fifths?

56 + StartFraction 28 over 5 EndFraction = 56 + 5 and three-fifths = 61 and three-fifths
56 times StartFraction 28 over 5 EndFraction = StartFraction 1568 over 5 EndFraction = 313 and three-fifths
15 + (StartFraction 35 over 5 EndFraction + four-fifths) = 15 + StartFraction 39 over 5 EndFraction = StartFraction 75 over 5 EndFraction + StartFraction 39 over 5 EndFraction = StartFraction 114 over 5 EndFraction = 22 and four-fifths
15 times (StartFraction 35 over 5 EndFraction + four-fifths) = 15 times StartFraction 39 over 5 EndFraction = StartFraction 15 over 1 EndFraction times StartFraction 39 over 5 EndFraction = StartFraction 585 over 5 EndFraction = 117

Answer 1

I have no clue as to what the options were, but the answer is 61 and three-fifths.

Explanation:

Well, the fraction options were a little distorted, so I'll work it out anyway.

7 • 8 4/5

7(8 + 4/5)

7 • 8 is 56, and 7 • 4/5 is 28/5.

56 + 28/5

28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.

56 + 5 + 3/5

61 + 3/5

61 3/5 (61 and three-fifths)

There!

(Sorry about not getting the options...)

Answer 2

A: 56+ 28/5 = 56 + 5 3/5 = 61 3/5
