Jason wants to cut a rope that is 60 feet long into several equal pieces with nothing left over. How many pieces will he have if
ale4655 [162]

Answer:

2 pieces, 30ft each

Step-by-step explanation:

rope : 60ft long

we are trying to figure out how many equal pieces we can cut the rope into with the length of each piece to be the greatest possible integer:

if jason wants the length of rope to be the longest than the answer is 2, if he divides the length of 60 by 2, each piece will be 30 feet long. If he divides the rope by any number larger, each piece will be shorter than 30 feet, and he wants the piece to be the largest possible length.

Drag the expressions to show the order of their quotients from least to greatest
Damm [24]

Answer:

by solving the divisions

Step-by-step explanation:

  • 8/9 ÷ 7/11 = 8/9 × 11/7 = 88/63 = 1.40
  • 19/12 ÷ 3/10 = 19/12 × 10/3 =190/36 = 5.28
  • 19/12 ÷ 1/15 = 19/12 × 15 = 285/12 = 23.75

8/9 ÷ 3/10 = 8/9 × 10/3 = 80/27 = 2.96.

now from the solutions you can get the least to greatest

1.40 , 2.96, 5.28 and 23.75
