Question

Hannah has some scraps of ribbon measuring 3.52 meters, 17.3 meters and 27.009 meters. Does she have enough to do a project requiring 50 meters of ribbon? If yes, how much ribbon will she have left? If no, how much more ribbon does she need?

Answer 1

No, 2.171m.

Explanation:

Add all of measurements. 3.52+17.3+27.009=47.829

Compare 2 numbers.

47.829<50

So she needs more ribbon,because the length she has is less the requirement, 50m.

Find the difference(the length she needs).

50-47.829=2.171
