Question

By how many millimetres the pencil in the image is longer than the eraser?

Answer 1

From the 'zero' mark, the pencil covers 6 cm and 5 mm
Length of the pencil = 6 cm 5 mm
= 6 x 10 + 5 (We know 1 cm = 10 mm)
= 65 mm

From the 'zero' mark, the eraser covers 2 cm
Length of the eraser = 2 cm
= 2 x 10
= 20 mm
Difference between the length of pencil and eraser = 65 - 20
= 45 mm
