Question
Fill in the blank: If $36 : 81 :: x : 63$, then $x =$ ......
✓
Answer
If $36 : 81 :: x : 63$, then $x =$ 28
If $36 : 81 :: x : 63$ Product of means = product of extremes
$81\text{x }=36\times63$ $\text{x}=\frac{2268}{81}$ $\text{x}=28$
If $36 : 81 :: x : 63$ Product of means = product of extremes
$81\text{x }=36\times63$ $\text{x}=\frac{2268}{81}$ $\text{x}=28$
