3:4•5

To solve the expression \( \frac{3}{4} \times 5 \), you can follow these steps:

1. First, convert the whole number \( 5 \) into a fraction: \( 5 = \frac{5}{1} \).
2. Multiply the two fractions:

\[ \frac{3}{4} \times \frac{5}{1} = \frac{3 \times 5}{4 \times 1} = \frac{15}{4} \]

So, \( \frac{3}{4} \times 5 = \frac{15}{4} \) or \( 3.75 \) in decimal form.
