Lets write out:
x =4, y = 10. Find y when x = 22.
[tex] \frac{4}{10}= \frac{22}{y} [/tex]
We need to find y. Lets do it:
10 × 22 = 220
220 ÷ 4 = 54
y = 54
Lets check:
[tex] \frac{4}{10}= \frac{22}{y} [/tex]
22 × 10 = 220
55 × 4 = 220
Yes, we are right!
y = 55
When x = 4, y = 10. Find y when x = 22.
When x = 22, y = 55.
Answer: y = 55
