how to you compare 8 fractions with different denominators including improper fractions?

• math -

Either change them to equivalent decimals or to fractions with the same denominators.

• math -

1. make them the same denominator, or
2. find the decimal equivalents for each.

• math -

how do you change them into equivalent decimals and same denominators?

• math -

For 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.

• math -

so 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 -

Divide the new denominator by the old denominator.

40/5 = 8

Multiply the old denominator by the quotient.

2 * 8 = 16

2/5 = 16/40

• math -

so 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)
