Question

Solve for n.

4/44 = n/77

A. n = 4

B. n = 7

C. n = 28

D. n = 264

Answer 1

`(4)/(44) =(1*4)/(11* 4)= (1)/(11) = (1* 7)/(11* 7) = (7)/(77)\\\\n= 7`

Your answer is B.

Another way to solve it is by cross multiplying.


`(4)/(44) = (n)/(77)\\\\4 * 77 = 44n\\\\n = (4* 77)/(44)\\\\n = 7`

Answer is B.
