Question

4 m - (30cm+40mm)=………………m

Answer 1

3.66m

Explanation:

First, we have units measured in meters, centimeters, and millimeters. This means we have to convert everything to the same measurement.

The easiest way is to convert everything to meters, as that's what the unit in the final answer will be.

To convert centimeters to meters, divide by 100

30/100=0.3

To convert millimeters to meters, divide by 1,000

40/1000=0.04

Next, plug the values back into the original equation:

4m-(0.3+0.04)

solve the parenthesis first

4-0.34

3.66

So, this equals 3.66 meters.

Hope this helps! :)

Answer 2

3.966m

Explanation:

4m - (30cm + 40mm)

Converting cm and mm to metre by dividing by 100 and 1000 respectively

=> 4.000m - (30/100 m + 40/1000 m)

=> 4.000m - (0.030m + 0.004m)

=> 4.000m - 0.034m

=> 3.966m
