PLS HELP ME ON THIS QUESTION I WILL MARK YOU AS BRAINLIEST IF YOU KNOW THE ANSWER PLS GIVE ME A STEP BY STEP EXPLANATION!! Which ratio is not equivalent to the others?
A. 27:45
B. 1520
C. 9:15
D. 3 to 5

B. 15:20

Step-by-step explanation:

27:45 = 3:5

15:20 = 3:4

9:15 = 3:5

3:5 = 3:5

All ratios except 15:20 are equal to 3:5.

B. 15:20

Step-by-step explanation:

The simplest of all ratios is 3 to 5 since they are prime numbers; therefore, all the ratios but 1 will equal to 3 to 5.

Ratio A:   27 and 45 have a common factor of 9 so when you do (27 ÷ 9) to (45 ÷ 9) you get 3:5.

Ratio B: 15 and 20 have a common factor of 5, so when you do (15 ÷ 5) to (20 ÷ 5), you get 3:4. 3:4 is not equivalent to 3:5.

Ratio C: 9 and 15 have a common factor of 3, so when you do (9 ÷ 3) to (15 ÷ 3), you get 3:5.

The only one that isn't equivalent to 3:5 is B.
