Nina can braid 144 inches of rope in 3 hours find her unit rate round your answer to the nearest thousand

48 inches

or

0.8 minutes

Step-by-step explanation:

To find the unit rate of inches per hour, divide 144 by 3.

144÷3=48

You don't need to round because there are no decimals.

To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour).

3×60=180

Then divide 144 by 180.

144÷180= 0.8

You don't need to round because there are no thousandths.

8 ×(7 + 12)

Step-by-step explanation:

Using the GCF you found in Part B, rewrite 56 + 96 as two factors. One factor is the GCF and the other is the sum of two numbers that do not have a common factor. Show your work.

Step.1

We find the factory of 56 and 96

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

Then the greatest common factor is 8.

Step 2

56 + 96 = 152

We have to find the other that is the sum of two numbers that do not have a common factor.

152 = 8 × 19

152 = 8 × (7 + 12)

Therefore:

56 + 96 = 8 × (7 + 12)
