Question

write using decimals 17m 80cm

Answer 1

We have,
17m 80cm
CONVERTING INTO CENTIMETRES
Hence,
1m=100cm
So, 17m = 1700cm
Therefore,
Total centimetres in 17m 80cm= 1780 cm

CONVERTING INTO METRES
Hence,
100cm =1m
So, 80cm = 0.8m
Therefore,
Total metres in 17m 80cm = 17.8m

Answer 2

Concept:

1 m = 100 cm

1 cm = 1 / 100 m

Given:

We are given the term:

17 m 80 cm.

Find:

We need to write it using decimals.

Solution:

We know that 1 m = 100 cm

So, we get that:

17 m = 17 × 100 cm

17 m = 1700 cm

17 m 80 cm = 1700 cm + 80 cm = 1780 cm.

Now we also know that:

1 cm = 1 / 100 m

1780 cm = 1780 / 100 m

1780 cm = 17.8 m.

Therefore, we can write 17 m 80 cm as 17.8 m in decimals.
