What do 1.6 meters plus 11 centimeters equal?

Answer 1

The centi- prefix (c) means 1/100

→ 1 cm = 1/100 m = 0.01 m

→ 100 cm = 100 × 1/100 m = 1 m

Convert to the same units then do the addition, either:

• convert to cm:

1.6 m = 1.6 × 100 cm = 160 cm

→ 1.6 m + 11 cm = 160 cm + 11 cm = 171 cm

• convert to m:

11 cm = 11 × 0.01 m = 0.11 m

→ 1.6 m + 11 cm = 1.6 m + 0.11 m = 1.71 m

Use the conversion which is easier to work with or is the required units of the answer.
