उत्तर
Here, each unit is divided into 4 parts.
∴ the denominator will be 4.
(1) Point B is on the 10th equal part on the left side of point O.
∴ B is `(-10)/4`.
(2) `1 3/4 = (4 xx 1 + 3)/4 = (4 + 3)/4 = 7/4`
Here, Point C is marked on the 7th equal part on the right side of point O.
∴ Point C indicates `1 3/4`.
(3) `5/2 = (5 xx 2)/(2 xx 2) = 10/4` True
Point D is marked on the 10th equal part on the right side of O.
∴ D denotes the number `10/4 = 5/2`
