Worked Solution
Step 1: Find the LCD of 3, 4 and 6.
Multiples of 6: 6, 12, 18 ...
12 is divisible by 3, 4 and 6, so LCD = 12.
Step 2: Convert each fraction to an equivalent fraction with denominator 12.
1/3 = 4/12
1/4 = 3/12
1/6 = 2/12
Step 3: Add the three fractions.
4/12 + 3/12 + 2/12 = 9/12
Step 4: Simplify.
9/12 = 3/4
Priya uses 3/4 tin of paint in total.
Correct answer: 3/4
