a) 8m 78cm = 8m + $\frac{78}{100}$m = $8\frac{78}{100}$m
b) 5m 5cm = 5m + $\frac{5}{100}$m = $5\frac{5}{100}$m
c) 3m 9cm = 3m + $\frac{9}{100}$m = $3\frac{9}{100}$m
a) 8m 78cm = 8m + $\frac{78}{100}$m = $8\frac{78}{100}$m
b) 5m 5cm = 5m + $\frac{5}{100}$m = $5\frac{5}{100}$m
c) 3m 9cm = 3m + $\frac{9}{100}$m = $3\frac{9}{100}$m
