A fraction, where the numerator is less than the denominator is called the proper fraction for example, \(\frac{2}{3}\), \(\frac{5}{7}\), \(\frac{3}{5}\) are proper fractions. Amixed number is an addition of its whole and fractional parts. 8+ 1 2 8 + 1 2. Add 8 8 and 1 2 1 2. Tap for more steps 17 2 17 2.
