Practice makes perfect
We want to complete the given statement using < or >.
10in. 200mm
To do so, we can convert the units of one term to have the same units on both sides of the inequality. Converting between inches (in.) and millimeters (mm) will involve using a conversion factor.
25.4mm/1in.
Multiplying 10in. by this conversion factor will convert it to millimeters.
This means that 10 inches is greater than 254 millimeters, so we will complete the given statement with the inequality symbol >.
10in. > 200mm
