Question

Deepak plotted these points on the number line. Point A: –0.3 Point B: – 3 4 Point C: – 11 4 Point D: –0.7 Which point did he plot incorrectly?

Answer 1

Answer:D

Explanation:

Answer 2

Point D is plotted incorrectly.

Explanation:

The points are given to be :

`A=0.3,B=(3)/(4),C=(11)/(4),D=0.7\\\\\implies\text{Points are : }A=(3)/(10),B=(3)/(4),C=(11)/(4),D=(7)/(10)`

Now, Points on a number line are plotted in the increasing order or ascending order. because the number line moves from left to right.

So, to check the point which is plotted incorrectly, arrange the given points in increasing order :

`(3)/(10)<(7)/(10)<(3)/(4)<(11)/(4)\\\\\implies\bf A<D<B<C`

So, the point D is plotted incorrectly. It would have been plotted after point A in order to plot the points correctly on the number line.

Hence, Point D is plotted incorrectly.
