Three-fourths of forty equals which number?

Explanation:
Understanding fractions of a number means multiplying the whole by the fraction. Three-fourths means three parts out of four, so you multiply forty by 3/4. Compute: 40 × 3/4 = (40 ÷ 4) × 3 = 10 × 3 = 30. Equivalently, 40 × 0.75 = 30. So the result is 30. Think of it as taking three of the four equal parts of forty. The other numbers would correspond to smaller pieces: half of forty is 20, a quarter is 10, and the whole forty would be 40.
