Madeline is making a quilt. She found some pieces of fabric on sale that each measured 9/10 of a yard. She is going to use 2 1/2 of the pieces for the quilt. What is the total length of the fabric she will use?

9/4 yards

Step-by-step explanation:

From the question,some pieces of fabric on sale that each measured 9/10 of a yard. And 2 1/2 of the pieces for the quilt is required to be used.

Then the total length of the fabric she will use can be calculated as

=(2 1/2 of the pieces)×(9/10 of a yard)

=( 5/2 of the pieces)× ( 9/10 of a yard)

= 5/2×9/10

= 45/20

Divide both the denominator and numerator by factor of 5, we have

=9/4

The total length of the fabrics she will use is 9/4 yards

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

its 4 because 2 times 2 is 4, if you double the number two you get four
