Simplify the ratio 3:2.1

Explanation

It sounds like you want the decimal number to become a whole number. If so, then one way is to multiply both parts by 10 to move that decimal point over one spot to the right

3*10 = 30

2.1*10 = 21

The ratio 3:2.1 is equivalent to 30:21

Then notice how 30 and 21 have the greatest common factor 3. Divide both parts by 3 so we can fully reduce this ratio

30/3 = 10

21/3 = 7

The ratio 30:21 simplifies fully to 10:7

The numbers 10 and 7 do not have any factors in common, other than 1, so we cannot reduce 10:7 any further.

i believe the answer is d.

hope it you! : d

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
