Question

Which pair of fractions shows 7/9 and 5/12 correctly converted with their least common denominator?

Answer 1

@DanJS

Answer 2

They want both fractions to have the same denominators

Answer 3

to do this, take multiples of 12, until you get a number that 9 will divide evenly into

Answer 4

Is it the same thing as last time?

Answer 5

sort of, you want to write both those fractions with the same denominators

Answer 6

the way i do it is, take multiples of the higher number, until you get a number that the smaller one will divide evenly into

Answer 7

12 * 2 = 24

9 will not divide evenly into 24

Answer 8

I think it is c.

Answer 9

12*3 = 36

9 does divide into 36 evenly

Answer 10

36 is the denominators, now you need to multiply each fraction top and bottom by a number to make the denominators 36

Answer 11

7/9 * 4/4 = 28 / 36

Answer 12

5/12 * 3/3 = 15 / 36

Answer 13

see what i did there?

Answer 14

34/36 and 29/36

Answer 15

no

28/36 and 15/36

Answer 16

Is that the answer?

Answer 17

K

Answer 18

yes, 36 is the least common denominator between 9 and 12

Answer 19

That is right!!!!

Answer 20

multiplied the first fraction by 4/4 and the second by 3/3, then both will be over 36

Answer 21
