Question

The ratio of the lengths of strings that play the notes F and G is 9 to 8. If a string 40 centimeters long plays a G, what is the length of the string that plays an F? Express your answer as an integer or mixed number.

F(length)/G(length) = 9/8 = F/40 cm

F = (9/8) x 40 = ?

The answer will be an integer in this case.
