Answer 3

To solve the proportion 39:x = 91:14, you can use the cross-multiplication method. Cross-multiplication involves multiplying the numbers diagonally across the equal sign and then solving for the unknown variable. Here's how you do it:

39/x = 91/14

Cross-multiplication: 39 * 14 = 91 * x

Now, solve for x: 546 = 91x

To find the value of x, divide both sides by 91: x = 546/91

x ≈ 6

So, the value of x is approximately 6.
