1/2g - 1/5

Step-by-step explanation:

You have to combine the ones that are the same, so the ones with the g and the ones without the g.

1/5g -g + 1 3/10 g = 1/2x

Just do the regular addition and subtraction and keep the variable.

-1/10 - 1/10 = 1/5

Regular subtraction (you need to know integer rules)

Final 1/2g - 1/5

For similar questions, know how to operate with fractions and the integer rules.
