Number & Operation 25

The teacher has 30 feet of rope. She cuts off pieces 4 feet long to make jump ropes for her class. Before she finishes, a student predicts that she will have 2 feet of rope left over.



Is the student correct? How do you know? Explain using words.

yes the student is right because the teacher can only make 7 jumps ropes. then that means she only used 28 feet of rope!

The student is right because the teacher would cut out 7 pieces of rope 4 feet long and that would be 28 feet of jump rope leaving a remainder of 2 feet.

The student is right. You will have 2 ft left over because 4 goes into 30, 7 times. 4 x 7 = 28. So there will be 2 ft left over.

She is right because 4x7=28. There is 2 feet left.

yes, there should be 2 ft. left over because if you multiply up by by 4 you get up to 7 and you have 28 ft. worth of jump ropes which leaves you with 2 ft. left over.
