Explanation:
Janice needs to read 2/3 of her book by Friday. So far she has read 1/2 of it. What part of the book must she still read by Friday?
This is solved using Subtraction
The part of the book she must read by Friday = 2/3 of the book - Fraction of the book that she has read
= 2/3 - 1/2
Lowest Common Denominator = 6
= (2 × 2) - (3 × 1)/6
= 4 - 3/6
= 1/6
The part of the book she must read by Friday = 1/6
