Lenny buys 5/8 yd. of ribbon for every 2yd. of fabric for a project. What is the unit rate of ribbon to fabric?
A. 5/8 / 2
B. 2 / 5/8
C. 5/16 / 1
D. 1 / 5/10
The unit rate of ribbon to fabric is the amount of ribbon (in yards) that is needed for every 1 yard of fabric.
To find the unit rate, you need to divide the amount of ribbon by the amount of fabric.
Lenny buys 5/8 yd. of ribbon for every 2 yd. of fabric.
Therefore, the unit rate of ribbon to fabric is: 5/8 / 2.
The correct answer is A. 5/8 / 2.
To find the unit rate of ribbon to fabric, we need to determine the amount of ribbon Lenny buys for 1 yard of fabric.
We know that Lenny buys 5/8 yd. of ribbon for every 2 yd. of fabric.
To find the unit rate, we divide the amount of ribbon by the amount of fabric.
Therefore, the unit rate of ribbon to fabric is:
5/8 / 2 = 5/8 × 1/2 = 5/16
Therefore, the answer is (C) 5/16 / 1.
To find the unit rate of ribbon to fabric, we need to determine how much ribbon is purchased for each unit of fabric. In this case, the unit of fabric is 2 yards.
To calculate this, we can divide the amount of ribbon purchased (5/8 yard) by the amount of fabric (2 yards).
The correct option for the unit rate of ribbon to fabric is:
A. 5/8 / 2
Explanation:
To divide a fraction by a whole number, we multiply the numerator (top number) by the reciprocal of the denominator (bottom number).
So, 5/8 divided by 2 can be written as 5/8 * 1/2.
Multiplying the numerators gives us 5 * 1 = 5.
Multiplying the denominators gives us 8 * 2 = 16.
Therefore, the unit rate of ribbon to fabric is 5/16.
Therefore, the correct option is A. 5/8 / 2.
