Four balls of wool will make 8 knitted caps how many balls will the girl need if she wants to make 6 caps

If 8 divided by four is two and that means there's two for each, then you would have three because 3 times two equals 6. So the answers 3 I think.

If the girl wants to make 6 knitted caps she will need 3 balls of wool. One ball of wool makes 2 caps.

8 / 4 = 2

6 / 3 = 2

She will need 3 balls of wool for 6 caps. 

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
