Question

Leslie uses 3/5 of a yard of ribbon for every 7 photo frames that she makes. How many yards of ribbon would Leslie need to make 20 photo frames?

Answer 1

Hi Ashley,

There is more than one way to approach this problem .

Using unit rates would be an option. If you determine how much ribbon would be needed for 1 frame (the unit rate), then you would just need to multiply by 20 for all of the frames. Let's use the variabke x to represent the ribbon needed for 1 frame:

3/5 yar = x

7 frames 1 frame.

Divide the numerator and denominator by 3/5 to find the amount of ribbon needed for 1 frame:

3/5 divided by 7 is 3/35 . Each frame requires 3/35 yards of ribbon.

Fir 20 frames, multiply 3/35 by 20:

3/35 * 20 = 12/7 yards needed for all frames.

Note - 12/7 yards is equivalent to 1 and 5/7 yards.
