Proportions- determine if each pair of ratios forms a proportion. show all work! 12/15 and 2/3

They do not form a proportion.

Step-by-step explanation:

To determine if they are a proportion, you can cross multiply and get the same answer on both sides. So, we multiply the numerator from the first by the denominator in the second.

12 * 3 = 36

Now we use the denominator from the first side and the numerator on the second side.

15 * 2 = 30

Since they are not equal, it is not a real proportion.

you do cross-multiply:

10.2(12)= 122.4

4(h)=4h

4h=122.4

h=30.6

if h is 30.6, it will be proportional

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
