Answer :
a. The number of pieces that Kelvin can cut if each piece is 0.4 meter long is 6 pieces.
b. The length of ribbon leftover is 0.2 meters.
The roll of the ribbon is 9 meters long. If he cuts 8 pieces and each piece is 0.8 meter long, the total length of the 8 pieces can be determined by multiplying the pieces cut by the length of each piece.
Total length cut = 0.8 meter x 8 = 6.4 meters
The total length that remains after he cuts the 8 pieces can be determined by subtracting the total length cut from the length oft the ribbon.
Length left = 9 meters - 6.4 meters = 2.6 meters
The length of each piece Kelvin would have if each piece is 0.4 meter long can be determined by dividing the length left by 0.4.
Number of pieces = 2.6 / 0.4 = 6.5 pieces
Thus he can cut the ribbon into 6 pieces.
The length of the ribbon leftover = 2.6 meters - (6 x 0.4)
2.6 - 2.4 = 0.2 meters

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
