Q. 95=X45\frac{9}{5} = \frac{X}{45}
  1. Set up proportion: Set up the proportion to solve for XX. We have the proportion 95=X45\frac{9}{5} = \frac{X}{45}. To find XX, we need to cross-multiply.
  2. Cross-multiply: Cross-multiply to find the value of XX.9×45=5×X9 \times 45 = 5 \times X405=5X405 = 5X
  3. Divide to solve: Divide both sides of the equation by 55 to solve for XX.\newline4055=5X5\frac{405}{5} = \frac{5X}{5}\newline81=X81 = X
