Question

What fraction of a complete rotation does the hour hand of a clock turn through, when it goes from 4 to 11?

• A. $1$
• B. $\frac{7}{12}$
• C. $\frac{1}{2}$
• D. $\frac{3}{4}$

Answer 1

The correct option is B $\frac{7}{12}$

We know that there are 12 divisions on the clock, so each divison accounts for $\frac{1}{12}$ of a rotation.
From 4 to 11, there are a total of 7 divisions,
Therefore, the amount of turn an hour hand should turn would be,
$7\times \frac{1}{12}=\frac{7}{12}$
