Question

The height of a chair is 1.15 m. A ladder is 650 cm higher than the chair. What is the height of the ladder?​

Answer 1

Answer:

• Height of chair = 1.15 m
• Height of ladder = 650 cm higher than chair.

Height of ladder in meters = 6.5m

Height of ladder = 6.15 + 1.15 = 7.65 m

Hence, we got the height of ladder = 7.65 m

Answer 2

Answer:

Given,

Height of Chair = 1.15m

Height of Ladder = 650cm more than 1.15m

Conversion

1m = 100cm

1cm = 1/100m

650cm = 650/100m

= 6.50m

Height of Ladder

Height of Ladder = 1.15m + 6.50m

= 7.65m

This can also be written as, 7m 65cm

This is because, 7.65 is 7m + 0.65m

1m = 100cm

0.65m = 0.65×100cm

= 65cm

So, 7m and 65cm
