Question

A number line going from negative 2 to 0 in increments of 1. There are 4 equal spaces between each number. Point D is between the second and third mark to the right of negative 2. Point C is 1 mark to the left of negative 1. Point B is 1 mark to the right of negative 1. Point A is between the second and third mark to the right of negative 1. 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? Point

Answer 1

D

Explanation:

Answer 2

Incorrect points : point D ; point A

Explanation:

Given that each number is in an Increment of 1;

4 equal spaces between each number = 1/4 = 0.25 (distance between successive tick mark)

Midpoint between two tickmarks = 0.25 / 2 = 0.125 = 1/8

Point B = 1 tick mark to the right of - 1

Point B = - 1 + 1/4 = - 3/4

Point C = 1 tick mark to the left of - 1

Point C = - 1 - 1/4 = - 1 1/4

Point D = (1/2 tick mark to the left of C)

1/2 tick mark = 1/4 ÷ 2 = 1/8

Point D = - 1 1/4 - 1/8 = - 1 3/8

Point A = (1 1/2 tickmarks to the right of B)

1 1/2 tickmarks = 0.375 = 3/8

Point A = - 3/4 + 3/8 = - 0.375 = - 3/8
