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.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

the answer

b. they are parallel and will never intersect.
