TO MAKE 5 SETS OF CURTAINS, WHEN EACH SET REQUIRES 2 1/3 YARDS, HOW MANY OF MATERIAL ARE NEEDED?
(1) 7 1/3
(2) 9 2/3
(3) 10 1/3
(4) 10 2/3
(5) 11 2/3
I think the answer is (5) 11 2/3??
Yes, (5) is right.
oh thank you , I have worked on that for hours!!:)
Congrats! Your hard work paid off! :-)
To find out how much material is needed to make 5 sets of curtains, you need to multiply the amount of material needed per set by the number of sets.
Each set requires 2 1/3 yards of material. To multiply this number by 5, you can convert the fraction 2 1/3 into an improper fraction or mixed number. In this case, 2 1/3 is already a mixed number.
So, to calculate the total amount of material needed, you can multiply 2 1/3 by 5:
2 1/3 * 5 = (2 + 1/3) * 5
Start by multiplying the whole numbers:
2 * 5 = 10
Now, multiply the fraction by the whole number:
(1/3) * 5 = 5/3
To add these results together, you need to have a common denominator. In this case, the common denominator is 3:
(10 + 5/3) = (30/3 + 5/3) = 35/3
Now, convert the improper fraction back into a mixed number:
35/3 = 11 2/3
Therefore, the correct answer is option (5) 11 2/3.
