Dustin has three lengths of rope: 3/4 yard long, 2/3 yard long, and 7/10 yard long. He needs at least 1 yard of rope. Which two pieces of rope together will be at least 1 yard in length and have the smallest amount left over?

Respuesta :

a think it is all of the above because each rope is the same amount
fisrt you have to find the common denominator, 60. 40/60, 45/60, and 42/60. the answer is 3/4 and 7/10
