Aroll of ribbon was 9 meters long. kevin cut 8 pieces of ribbon, each of length 0.8 meter, to tie some presents. he then cut the remaining ribbon into some pieces, each of length 0.4 meter.
a) how many pieces of ribbon, each 0.4 meter in length, did kevin have?
b.) what was the length of ribbon left over?
( explain how you got your answer) ( ! )

6 pieces

0.2 left over

Step-by-step explanation:

Start by multiplying 8 by 0.8 to see the amount of ribbon used for those pieces

8 × 0.8 = 6.4

Then subtract 6.4 from 9 which should give you 2.6

9 - 6.4 = 2.6

Then divide 2.6 by 0.4 which gives you 6.5

2.6 ÷ 0.4 = 6.5

So you have 6 pieces

The .5 is half of 0.4 so the left over is 0.2
