H = 1, P =2, R = 3 B = -1, C = -2, A = -3, Q = -5

Step-by-step explanation:

For the first number line:

From the tick mark to the tick mark with 4, there are 4 tick marks

Distance from 0 to 4 = 4 - 0 = 4

Each tick mark = 4/4 tick marks

Each tick mark = 1

This means each tick mark increases by 1 to the right after 0 and decreases by one to the left before zero.

H, P and R are after 0

H = 0 + 1 = 1

P = 1 + 1 = 2

R = 2 + 1 = 3

B, C, A and Q are all before 0

B = 0 - 1 = -1

C = -1 - 1 = -2

A = -2 - 1 = -3

Q = -4 - 1 = -5

For the 2nd number line:

from 0 to 100, there 5 tick marks

Distance from 0 to 100 = 100 - 0 = 100

Each tick mark = 100/5 tick marks

Each tick mark = 20

This means each tick mark after zero increases by 20 to the right and decreases to the before 0 by 20.

A, L and M are after zero

Number before A is 20, increasing the number by 20

A = 20 + 20 = 40

L = 40 + 20 = 60

M = 60 + 20 = 80

J, P, T, V are before zero

Number before J = 0, decreasing by 20

J = 0 - 20 = -20

P = -20 - 20 = -40

T = -40 - 20 = -60

V = -60 - 20 = -80
