18 x 2/5 = 36/5 = 7 1/5m
7 1/5 m = 7m 20cm
18m - 7m 20cm = 10m 80cm
1/5 m = 20cm
10 m 80cm = 1080 cm
1080 / 20 = 54 pcs
7 1/5 m = 7m 20cm
18m - 7m 20cm = 10m 80cm
1/5 m = 20cm
10 m 80cm = 1080 cm
1080 / 20 = 54 pcs
The original rope is 8m not 18m

It is not necessary to always change fraction to decimal. You use (fraction/decimal) whichever suits you best.
