Lenny buys 5/8 yd. of ribbon for every 2 yd. of fabric for a project. What is the unit rate of ribbon to fabric?

A. 5/2 /2

B. 2/ 5/8

C. 1/ 5/10

D. 5/16 /1

To find the unit rate of ribbon to fabric, we need to divide the amount of ribbon by the amount of fabric.

If Lenny buys 5/8 yard of ribbon for every 2 yards of fabric, the unit rate of ribbon to fabric would be:
(5/8) / 2 = 5/8 * 1/2 = 5/16

Therefore, the correct answer is D. 5/16 / 1.

To find the unit rate of ribbon to fabric, we need to divide the amount of ribbon purchased by the amount of fabric used.

Lenny buys 5/8 yd. of ribbon for every 2 yd. of fabric.

So, the unit rate of ribbon to fabric is:

(5/8 yd. of ribbon) / (2 yd. of fabric)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

Reciprocal of 2 yd. of fabric = 1/2 yd. of fabric

So, the unit rate is:

(5/8 yd. of ribbon) * (1/2 yd. of fabric)

Multiplying the fractions gives us:

(5/8) * (1/2) yd. of ribbon per yd. of fabric

Simplifying further:

5/16 yd. of ribbon per yd. of fabric

Therefore, the unit rate of ribbon to fabric is 5/16.

The correct answer is D. 5/16 /1.

To find the unit rate of ribbon to fabric, we need to determine how much ribbon is purchased per yard of fabric.

The given information states that Lenny buys 5/8 yd. of ribbon for every 2 yd. of fabric.

To find the unit rate, we need to divide the amount of ribbon by the amount of fabric.

The unit rate can be determined by dividing the amount of ribbon (5/8 yd.) by the amount of fabric (2 yd.).

So, the unit rate of ribbon to fabric is:

(5/8) / 2 = 5/16

Therefore, the correct answer is D. 5/16 /1.
