m = 60h
Answer:
1300 mm
Step-by-step explanation:
You want to convert metres to millimetres, so you multiply the metres by a conversion factor:
1.3 m × conversion factor = x mm
1 m = 1000 mm.
So, the conversion factor is either (1 m/1000 mm) or (1000 mm/1 m).
We choose the latter, because it has the desired units on top.
The calculation becomes

But these things will change direction of the inequality:
Don't multiply or divide by a variable (unless you know it is always positive or always negative)
