a piece of yellow yarn was 230 inches long. After 90 inches had een cut from it,,, the piece of yellow yarn was twice as longas
jasenka [17]
Okay. So 90 yds was cut from the 230 yd yarn. 230 - 90 = 140. 1/2 of 140 is 70. 230 - 70 = 160. The yellow yarn was 160 yds longer than the blue yarn at first.
