14.4 is to m creates the fraction:
14.4
------
m
7.2 is to 6 creates the fraction:
7.2
----
6
the word as in the middle means the two fractions are equal giving you the proportion:
14.4 = 7.6
------ -----
m ____ 6
Solve for m by cross multiplying. To do this multiply the numbers diagonal from each other and set those cross products equal to each other:
7.2(m) = 14.4(6)
Simplify:
7.2(m) = 86.4
Now divide by 7.2 on both sides to get m by itself. This leaves you with:
m = 12

The solution is a classic cross-multiply.
Write the proportion as 14.4/m = 7.2/6
Then multiply the first bottom by the second top and multiply the second bottom by the first top.
That gets you (14.4 x 6) = 7.2m
Now divide both sides by 7.2
That gets you m = 12, the answer

the formula is: 14.4 : M :: 7.2 : 6
which means 14.4 is to M as is 7.2 is to 6
either you multiply the two end numbers if there are two end numbers
or you multiply the two inside numbers if there are two inside numbers.
Then you divide by the number left over.
In this case you must multiply the two end numbers cause there are two end numbers but only one inside number
so the equation becomes 14.4 x 6 divded by 7.2 = 12

A proportion is a quotient.
14.4/m = 7.2/6
Sove for m.

The second part is easier - as 14.4 is twice 7.2 the answer must be 12.
7.2:6 simplifies as 1.2:1 or 120%

14.4/m=7.2/6 or m=14.4*6/7.2
then, m=12 m is proportional

taking it from ratio perspective, as it is 14.4 : m, and 7.2 :6. if you take the two numbers together and cross myltiply you will definately get the answer as 12.

14.4/m = 7.2/6
As you can see the numerator of the first is twice the second one...this means the first denominator must be twice the second.
Therefore m = 12

14.4/m = 7.2/6
First: get rid of the fractions > multiply the denominators by everything >
(6)(m)(14.4/m) = (6)(m)(7.2/6)
Sec: cancel "like" terms and combine the remaining terms >
(6)(14.4) = (m)(7.2)
86.4 = 7.2m
Third: solve for "m" by isolating it on one side > divide everything by 7.2 (opposite side means opposite sign >
86.4/7.2 = 7.2m/7.2
12 = m
m = 12

14.4 is double 7.2, thus m is double 6, therefore m=12
