Mass

Mr Vinc Chin

Convert the units of gram (g) to kilogram (kg)

4520 g = ____ kg

13700 g = ____ kg

690 g = ____ kg

8.03 kg = ____ g

= 8.03 x 1000

= 8030 g

13.05 kg = ____ g

= 13.05 x 1000

= 13050 g

2 kg 75 g = ____ g

= 2 x 1000 + 75

= 2000 + 75

= 2075 g

6 kg 130 g = ____ kg

= 6 kg + ( 130 ÷ 1000 ) kg

= 6 kg + 0.13 kg

= 6.13 kg

Addition of Mass

= 0.763 kg + 895 g + 1.565 kg

= 763 g + 895 g +1565 g

= 3223 g

​

= 0.53 kg + 8505 g + 3.031 kg

= 0.53 kg + 8.505 kg + 3.031 kg

= 12.066 kg

​

​

Subtraction of Mass

= 6.02 kg - 845 g 

= 6020 g - 845 g

= 5175 g

= 3.08 kg - 942 g

= 3.08 kg - 0.942 kg

= 2.138 kg

​

Multiplication of Mass

= 17 x 0.59 kg

= 10.03 kg

= 10.03 x 1000

= 10030 g

= 100 x 756 g

= 75600 g

= 75600 ÷ 1000

= 75.6 kg

Division of Mass

= 37.8 kg ÷ 24

= 1.575 kg

= 1.575 x 1000

= 1575 g

= 5.23 kg ÷ 100

= 0.0523 kg

= 0.0523 x 1000

= 52.3 g

0.655 kg x 18 =

0.655 kg x 18 =

= 0.655 kg x 18

= 11.79 kg
