Question

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?

1/6

Step-by-step 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
