To find the value of m in the following expression, set up a proportion and then find the desired variable by cross multiplying.
Given ratios: 14:21 and 7:m
Set up a proportion by setting these ratios equal to each other.
[tex]\sf{\cfrac{14}{21}=\cfrac{7}{m}}[/tex]
We can now use cross-multiplying to find m:
[tex]\sf{14m=147}[/tex]
Isolate m:
[tex]\underline{\underline{\sf{m=10.7}}}[/tex]
Answer: 10.5
Step-by-step explanation:
given 14:21 and 7: m
so , 14 / 21 = 7 / m
14m = 7 x 21 (cross product)
m = 21/ 2
m = 10.5
