**Ms. Sue**, Tuesday, February 14, 2012 at 4:54pmEither change them to equivalent decimals or to fractions with the same denominators.

**bobpursley**, Tuesday, February 14, 2012 at 4:54pm1. make them the same denominator, or

2. find the decimal equivalents for each.

**john**, Tuesday, February 14, 2012 at 4:57pmhow do you change them into equivalent decimals and same denominators?

- math -
**Ms. Sue**, Tuesday, February 14, 2012 at 5:01pmFor decimals, divide the numerator by the denominator.

Example: 3/4 = 0.75

For fractions, find a common multiple of the denominators.

Examples: 2, 3, 4, >> the common multiple is 12.

**john**, Tuesday, February 14, 2012 at 5:05pmso it's like you do this ->

2,4,6,8,10,12

3,6,9,12,15,18,21

4,8,12,16,20

and one more question, what about the numerators?

like if you're comparing 3/8 to 2/5 the common multiple is 40. the numerators?

- math -
**Ms. Sue**, Tuesday, February 14, 2012 at 5:14pmDivide the new denominator by the old denominator.

40/5 = 8

Multiply the old denominator by the quotient.

2 * 8 = 16

2/5 = 16/40

**john**, Wednesday, February 15, 2012 at 6:17pmso it would be like, 5/8 ? 6/7

8,16,24,32,40,48,56,64

7,14,21,28,35,42,49,56

LCD IS 56

so now i do 56/7=8*6=48 6/7=48/56

56/8=7*5=35 so, 5/8=35/56

5/8 (35/56) < 6/7 (48/56)
