Solving (1): What is asked

The requirement of the question is to determine the difference between the amount of sugar used between yesterday and today

Solving (2): The given facts

`Yesterday = (9)/(10)kg`

`Today = (3)/(5)kg`

Solving (3): Operation to be used

We use subtraction operation

Solving (4): The mathematical sentence

`D = Yesterday - Today`

`D = (9)/(10)kg - (3)/(5)kg`

D represents the difference

Solving (5): The solution

`D = (9)/(10)kg - (3)/(5)kg`

Take LCM

`D = (9 - 6)/(10)kg`

`D = (3)/(10)kg`
