Previous height in inches = 1 inch/2.5 cm x 135 cm/1.Multiply the numerators (1 x 135 = 135).Multiply the denominators (2.5 x 1 = 2.5).135/2.5 = 54 inches.Current height in inches = 1 inch/2.5 cm x 140 cm/1.Multiply the numerators (1 x 140 = 140).Multiply the denominators (2.5 x 1 =1).140/2.5 = 56.56 - 54 = 2 inches.The child has grown 2 inches since the last measurement.
