please mark me as brainlist

Step-by-step explanation:

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
