Which ratio is not equivalent to the other three? A. 2/5 B. 12/25 C. 6/15 D. 18/45.

Answer 1

c because if you add them together

Answer 2

1 - D

2 - D

3 - B

4 - B

Explanation:

Ques 1: Let the temperature in Tampa be denoted by X°F

It is given that the temperature never reaches below 40°F

The inequality representing the given situation is
`X\geq 40`.

So, D is correct.

Ques 2: Let the times Sarah read = S and the times Joel read = J.

It is given that Sarah read 3 more times than that of Joel and she read 9 times.

So, the equation becomes,
`S=J+3` i.e.
`9=J+3`

So, option D is correct.

Ques 3: Since, 1 inch = 2.54 centimeters

So, 4.5 inch =
`(2.54)/(1)* 4.5` = 11.4 centimeters

Thus, option B is correct.

Ques 4: As we have that,
`(2)/(5)=(6)/(15)=(18)/(45)`

So, the ratio not equivalent to others is
`(12)/(25)`.

So, option B is correct.
