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

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.

Well I have no idea how you arrived at your answer

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

To set up an equation to find the number of balls of wool Erika needs to finish the blanket, you can use the relationship between the amount of wool used so far and the progress made on the blanket.

Let's start by defining the variables:
Let x be the total number of balls of wool needed to finish the blanket.

From the information given, Erika has already used 10 balls of wool. We can represent this as 10.

Now, let's determine the progress made on the blanket. It is mentioned that Erika has completed 5/8 of the blanket. This means that 5/8 of the total number of balls of wool needed is equal to the 10 balls of wool she has used. We can represent this proportionally as:

(5/8) * x = 10

To solve this equation for x, we need to isolate the variable. We can do this by multiplying both sides of the equation by the reciprocal of 5/8, which is 8/5:

(8/5) * (5/8) * x = (8/5) * 10
x = 16

Therefore, Erika will need 16 - 10 = 6 more balls of wool to finish the blanket.

To summarize, the equation to find the number of balls of wool Erika needs to finish the blanket is:
(5/8) * x = 10
Solving for x, we get x = 16.
Thus, Erika will need 6 more balls of wool to finish the blanket.
