If x : 12 = 5 : 6, what is the value of x?
10
Write the ratio statement as an equation of fractions: \( \frac{x}{12}=\frac{5}{6} \).
Cross-multiply: \( 6x=5\times12=60 \).
Divide both sides by 6: \( x=\frac{60}{6}=10 \). Check: 10 : 12 reduces to 5 : 6 on dividing by 2.
Hence, the value of x is 10.
