Express as metres using decimals.
(a) 15 cm
(b) 6 cm
(c) 2 m 45 cm
(d) 9 m 7 cm
(e) 419 cm

Solution:

As we know that 1 m = 100 cm.

To convert cm into metre we will divide and express them as decimals.

(a) 15 cm

15 / 100 = 0.15 m

(b) 6 cm

6 / 100 = 0.06 m

(c) 2 m 45 cm

(2 × 100 + 45) / 100 = 245/100 = 2.45 m

(d) 9 m 7 cm

(9 × 100 + 7) / 100 = 907/100 = 9.07 m

(e) 419 cm

419 / 100 = 4.19 m
