Question

Jaime has two fractions, 3/18 and 13/15, that he needs to compare. He knows he will not be able to tell which is bigger until they have been rewritten with the same denominator. Which of the following shows both of these fractions rewritten with their least common denominator?

Answer 1

3/18= 1/6= .166

13/15= .866

3/18 < 13/15

Another way is

15/90 for 3/18

78/90 for 13/15

3/18 < 13/15

lcd: 90
