If it takes 9 3/4 yards of material to make curtains for 3 windows, how much material is needed?

Step-by-step explanation:

This is a rate problem, so we will write rate as a proportion and write the desired rate with x for the unknown value we need to find.

9.75/3 = x/1

Cross-mulitply

3x = 9.75

Divide by 3

x = 3.25 or 3 1/4

Another great thing with proportions is that we can check them to ensure we got the correct answer. All we do is substitute our determined value in for x

9.75/3 = 3.25/1

9.75 = 9.75 ✅

The answer of x = 3 1/4 is correct.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
