​

Answer 1

have to convert it to meters using decimals.

We know that 1 meter has 100 centimeters in it.

2 meters has 200 centimeters in it.

In the same way, 1m=100cm→1cm=1100m

1 centimeter is one hundredth of one meter.

We need to find how many meters is 15cm.

1cm=1100m15cm=?15cm=15×1100m=15100m

In decimals, 1100=0.01

Convert 15 cm into decimal meters.

1100=0.0115100=15×1100=15×0.01=0.15

Therefore, 15100m is equal to 0.15m in decimals.

15cm is 0.15 meters in decimal meters.
