A 10 meters yarn was cut into 5 equal parts. If 3 parts were used for crocheting, how long was used for crocheting?
assistant
How long is each part? ** Each part is 10/5 = <<10/5=2>>2 meters long.
How many meters of yarn were used for crocheting? ** Therefore, 2 x 3 = <<2*3=6>>6 meters of yarn were used for crocheting.
