Question

Danny bought 8 rolls of paper towels. He has 204.8 meters of paper towels in all. How many meters of paper towels are on each roll? A) 21.52 B) 25.12 C) 25.60 D) 26.52

Answer 1

204.8/8

Explanation:

Assume each roll has the same amount of paper towels.

You have 204.8 meters of paper towels spread equally between 8 rolls. Use division.

204.8/8

If you can't use a calculator, change the 8 into something simpler (8=2×2×2).

204.8/(2×2×2) = 204.8/2/2/2

Do one part at a time, left to right.

204.8/2 = 102.4

102.4/2 = 51.2

51.2/2 = 25.6

Answer 2

C. 25.6

Explanation:

8(m)= 204.8

divide 8 on both sides 8 and 8 cancel out 204.8/8=25.6, so m=25.6.
