Question

determine whether the ratio in each pair can form a proportion by finding a common multiplier 45/60 , 3/4

Answer 1

45/3 is it equal to 60/4 ?

Answer 2

huh

Answer 3

since you want to find a common multiplier for your ratios, it must mean that for some factor X times 3 it will give you 45, and with the same factor X times 4 it will give you 60. Are there such factors? try calculating 45/3 and 60/4 see what number you get and if it is the same number in both case

Answer 4

15

Answer 5

yup thats right

Answer 6

so how do i write it on paper ... is it 15 x 3 and 15x 4 so 45/60

Answer 7

question how do i do 7/8 15/24 ... do i cross multiply 120 168

Answer 8

3/4 * 15/15 = 45/60

Answer 9

7/8 does not equal 15/24 if that's what you are wondering

Answer 10

i dont know ... the question just says determine whether the ratio in each pair can form a proportion by using cross products

Answer 11

okay trying doing 15/7 and 24/8 if those numbers are not the same then you don't have equality

Answer 12

i have a silly question ... do i have to multiply or divide?

Answer 13

in this case divide

Answer 14

192 105

Answer 15

2.142857142 thats 15/7 and 24/8 3

Answer 16

yup so these numbers are not equal, it means the ratios 7/8 does not equal 15/24

Answer 17

are you there?
