The answers to the worksheet

Answer 1

An arithmetical operator used for converting a quantity expressed in a set of unit into an equivalent in another set of units are known as conversion factor.

The base SI units for length is meter,
`m`.

The conversion of
`m` to other relevant units are as:

`1 m = 100 cm`

`1 m = 1000 mm`

So,
`1 cm = 10 mm`

Now converting the given units as:

1a.

Since,
`1 cm = 0.01 m`

So,
`995 cm = 9.95 m`

2a.

Since,
`1 cm = 10 mm`

So,
`0.5 cm = 5 mm`

3a.

`2.79 cm = 27.9 mm`

4a.

Since,
`1 mm = 0.1 cm`

So,
`718 mm = 71.8 cm`

5a.

`36.6 cm = 366 mm`

6a.

Since,
`1 m = 100 cm`

So,
`3.6 m = 360 cm`

7a.

`51 mm = 5.1 cm`

8a.

`29 mm = 2.9 cm`

9a.

`32 mm = 3.2 cm`

10a.

Since,
`1 cm = 10 mm`

So,
`38.8 cm = 388 mm`

1b.

Since,
`1 mm = 0.1 cm`

So,
`209 mm = 20.9 cm`

2b.

Since,
`1 cm = 0.01 m`

So,
`862 cm = 8.62 m`

3b.

`36 mm = 3.6 cm`

4b.

`497 mm = 49.7 cm`

5b.

`134 cm = 1.34 m`

6b.

`3.1 cm = 31 mm`

7b.

`1.28 m = 128 cm`

8b.

`19.35 cm = 193.5 mm`

9b.

`0.4 m = 40 cm`

10b.

`1.87 m = 187 cm`
