1

kg = 0.5 kg

To find:

Work out the total mass in kilograms.

Solution:

One of the masses of the three bags is given in terms of grams, so to work out the total mass in kilograms, we have to convert grams into kilograms.

We have,

1 \:gram = \frac{1}{1000} \: kilograms1gram=

1000

1

kilograms

∴ 75 \:g = \frac{75}{1000} \:kg = 0.075\:kg75g=

1000

75

kg=0.075kg

Now, we will work out the total mass of the 3 bags of flour:

Total Mass = 1.2 \:+\:0.075\:+\:0.5=1.2+0.075+0.5= \bold{1.175\:kg}1.175kg ← option (1)

Thus, the total mass of the 3 bags of flour in kilograms is 1.175 kg.
