Solve proportions by finding the missing value in a/b = c/d equations with MaiCalcs. Uses cross multiplication method with step-by-step solutions.
Instructions: Enter exactly 3 values and leave 1 field empty. The calculator will solve for the missing value using cross multiplication.
• a/b = c/d
• Cross multiply: a × d = b × c
• Solve for the unknown variable
• Solve: 3/4 = x/12
• 3 × 12 = 4 × x
• 36 = 4x → x = 9
