2. \( 7: 8=X: 32 \)

To solve the proportion \( 7: 8 = X: 32 \), you can use cross multiplication. This means multiplying across the equals sign: \( 7 \times 32 = 8 \times X \). Doing the math gives \( 224 = 8X \). To isolate \( X \), divide both sides by 8, resulting in \( X = 28 \). Now, you're ready to put this knowledge to use! Understanding ratios like this is super handy in real life—be it cooking (scaling recipes up or down), mixing paints for that perfect shade, or even adjusting financial budgets!
