Question

Tara read 1/3 of a book on Monday, 2/7 of the book on Tuesday, and 2/9 of the book on Wednesday. How much of the book did she read?

Answer 1

Hello! So what we have to do is find the least common denominator for 3, 7, and 9, which is 63. 1/3 is 21/63, 2/7 is 18/63, and 2/9 is 14/63. The denominator stays the same. But add the numerators together. 21 + 18 + 14 is 53. Tara has read 53/63 of the book.

Answer 2

I can help you :) First, you need to find the common denominator in equation.
