Answer: 6=n
Step-by-step explanation:
You can write these as ratios. 4:n is the same as 4/n. 6:9 is the same as 6/9.
You set 4/n equal to 6/9 and solve for n.
4/n=6/9
You then cross multply since the fractions are equal to each other.
4*9=n*6
36=6n
6=n
To check work plug 6 back in for n, 4/6=6/9 to check work. The final answer is 6=n
