Answer Choices:
X = 12.5
🧮Proportions are solved by using the cross-multiplication method to find an unknown value in two equal ratios.
📐The ratio 4:10 means 4 divided by 10, and we set this equal to 5 divided by X to maintain the proportional relationship.
🔢By cross-multiplying, we calculate 4 × X = 10 × 5, which gives us 4X = 50.
🧾Finally, dividing both sides by 4 gives X = 12.5, making this the correct and mathematically sound answer.
Use cross-multiplication to solve ratios and proportions accurately and isolate the missing value.
