4n+10-10=18-10              4n-13+13=23+13               10n+8-8=78-8
4n=8                                 4n=36                                 10n=70
n=2                                   n=9                                      n=7

leva [86]

Answer:

the ratio would be 6.75:4.5:3:2

Step-by-step explanation:

d=2 and c=3

Then using proportion multiplication, you will find that b is 4.5

now replace all b with 4.5.

Then again using proportion multiplication, you will get a is 6.75.

Plug in a, b, c, d in the ratio and you get 6.75:4.5:3:2
