Question

20 metre 30 centimetre - 17 metre 60 centimetre answer​

Answer 1

Step-by-step explanation:

SOLUTION

We cannot subtract 60 cm from 30 cm. So,convert 1 m = 100 cm

∴ 2 m 70 cm.

Answer 2

Answer:

30 centimeters= 0.3 metre.

then 20+0.3= 20.3

also,

60 centimeter= 0.6

then 17+0.6=17.6

so,

20.3-17.6

=2.7
