Juan needs 3/4 yard of fabric to make a pillow case. How many yards of fabric will Juan need to see 5 pillow cases

Easy you just need to multiply 3/4 by 5 this is how you do it

You multiply 5 x 3 = 15 so it's 15/4 but 15/4 is greater than 1 so 4 goes into 15 three times so that's 3 x 4 = 12 then you 15 - 12 = 3 so your answer is 3 3/4
