Question

What is the sum of 6 dm, 40 mm, 2 m, and 10 cm in meters?

Answer 1

Answer: 800

Explanation:

Answer 2

Answer: 2.74 m

Explanation:

You need to make the following conversions:

• From 6 dm to m (Remember that
  `1m=10dm`), then you get:

`(6dm)((1m)/(10m))=0.6m`

• From 40 mm to m (Remember that
  `1m=1,000mm`), then you get:

`(40mm)((1m)/(1,000mm))=0.04m`

• From 10 cm to m (Remember that
  `1m=100cm`), then you get:

`(10cm)((1m)/(100cm))=0.1m`

Now you need to add all the values to get the sum. This is:

`0.6m+0.04m+2m+0.1m=2.74m`
