Question

If a picture of a board is 35 mm and that board is 20.5", how many inches does 42 mm equal?

Donagan

Top Answerer

Use cross-multiplication. Set up the equation 35 / 20.5 = 42 / x, where x is the dimension you're looking for in inches. Cross-multiply: 35x = (20.5)(42). 35x = 861. Divide both sides by 35: x = 861/35 = 24.6 inches.
