To make 5 sets of curtains, when each set requires 2'1/3 yards, how many of material are needed ?
7/3 * 5 = ?
To find out how much material is needed to make 5 sets of curtains, we need to multiply the amount of material required for each set by the total number of sets.
Each set requires 2'1/3 yards of material. To convert this mixed fraction to an improper fraction, we multiply the whole number (2) by the denominator (3), and then add the numerator (1). Then, we divide the result by the denominator to get the improper fraction:
2 * 3 + 1 = 7
7 / 3 = 2'1/3
So, each set requires 2'1/3 yards of material.
To calculate the total amount of material needed for 5 sets, we multiply the amount of material required for one set by the number of sets:
2'1/3 * 5 = (2 + 1/3) * 5 = 10 + 5/3
To add the whole numbers, multiply the denominator (3) by the whole number (10), then add the result to the numerator (5):
3 * 10 + 5 = 30 + 5 = 35
Therefore, 5 sets of curtains require a total of 35 yards of material.
