Question

Leah cut a 7\1\2 inch piece of ribbon into pieces that are each 3\4 of an inch long. How many pieces of ribbon did she cut?

Answer 1

(7 1/2) / (3/4) =
(15/2) / (3/4) =
15/2 * 4/3 =
60/6 = 10 pieces

Answer 2

She cut 10 pieces.

Explanation:

Length of a ribbon cut by Leah is given as
`7(1)/(2)` inch or
`(15)/(2)` inch.

Now she cuts this length into small pieces of
`(3)/(4)` inch.

So we have to find the number of pieces she cuts.

Let number f small pieces of ribbon are = x

then length of x pieces will be =
`(3)/(4)`(x)

Total length of small pieces =
`(15)/(2)` inch.

`(3x)/(4)` =
`(15)/(2)`

x =
`(15)/(2)` ×
`(4)/(3)`

= 5 × 2

= 10 pieces.

She cut 10 pieces.
