Sarah gave the same answer when asked to round 4 7/8 to the nearest inch and half a inch. explain why sarah is correct.

When you take 4 7/8 and round it up to the next inch u round up because 7/8 is bigger than 1/2 so thats 5
u would round it up to 5  again for the nearest half inch because 7/8 is closer to 1 than 1/2 which brings it to 5 

The amount used= 13.04- 1.9 = 11.14
