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
[tex]Yesterday = \frac{9}{10}kg[/tex]
[tex]Today = \frac{3}{5}kg[/tex]
Solving (3): Operation to be used
We use subtraction operation
Solving (4): The mathematical sentence
[tex]D = Yesterday - Today[/tex]
[tex]D = \frac{9}{10}kg - \frac{3}{5}kg[/tex]
D represents the difference
Solving (5): The solution
[tex]D = \frac{9}{10}kg - \frac{3}{5}kg[/tex]
Take LCM
[tex]D = \frac{9 - 6}{10}kg[/tex]
[tex]D = \frac{3}{10}kg[/tex]
