OPERATIONS ON METRIC MEASURES

We can perform fundamental operations: addition,
subtraction, multiplication and division (+, –, ×, ÷) Note

on metric measures of the same units. Units of measurement are added or
subtracted in the same way as we add
To do this, first convert given metric measures into or subtract whole or decimal numbers.
the same units before performing any operation on

them.
Example 1: Add the following.

(a) 24 m 24 cm and 7 m 12 mm

(b) 3 kg 7 hg 5 dag 3 g 4 dg 5 cg 2 mg and 5 kg 7 hg 2 dag 1 dg 4 cg 4 mg

(c) 15 L 725 mL and 11 L 850 mL

Teacher’s
Tip Inform the children that the units of measurement we generally used are m, cm, km, g, kg, L, kL. Other units
of measurements such as hecto, deca and deci are generally not used in real life.
