Kelly has read 5/6 of a book Helen has read 9/12 of the same book who has read more of the book

Answer 1

If both fractions had the same denominator, you could quickly decide. The least common denominator for 6 and 12 is 12.

Therefore, we can multiply the numerator and denominator by 2 to find a equivalent fraction for 5/6 with a denominator of 12:

5/6 *2/2 = 10/12

Since 10/12 is greater than 9/12, Kelly read more than Helen.

Answer 2

Express both fractions with the same denominator and then compare.

5/6 = 5/6 x 2/2 = 10/12

Noe that 10/12 > 9/12, so 5/6 > 9/12.
