Question

Erika is weaving a wool blanket. So far, she has used 10 balls of wool and has completed 5/8 of the blanket. How many more balls of wool will Erika need to finish the blanket?

How would I set up an equation to find the number of balls of wool Erika need to finish the blanket? I know that 5/8 is actually 3/8x. If I do a strip diagram, I will have 8 blocks and 5 of those blocks are crossed out leaving 3 blocks remaining. Each of the blocks will be 2. So 10/3 = 5/3. Then the equation is 3/8x = 5/3 and the answer is 9/40

Not sure if I did it correctly

Answer 1

she has used 10 balls of wool and has completed 5/8
so, 2 balls is 1/8 of the blanket

that means the whole blanket uses 16 balls
with 3/8 left to do, that will require 6 more balls.

I have no idea how you arrived at your answer, but maybe you can figure out how to modify your steps to arrive at the above answer.

Answer 2

Well I have no idea how you arrived at your answer

Answer 3

(3/8)/(5/8) * 10balls = 3/8*8/5 * 10 = 6 more balls.
