We start by writing the ratio

and

as fraction

This shows two pairs of equivalent fractions

and

We will use the first pair of fraction

⇒ cross multiply gives

⇒ then rearrange

⇒ which we can also write in form of ratio

Hence it is proved that

as required
Point B . 1 Mark to the right of negative 1
Step-by-step explanation:
The given number line starts from negative 2 to positive 1 in increments of 1.
Hence the four main divisions represent negative 2, negative 1 0 and positive 1
Also there are 4 equal spaces between each number. Hence each sub division between each number represents a quarter.
Point A is 1 mark to the right of negative 2. This would represent the number negative one and three quarter.
Point B is 1 mark to the right of negative 1. This would represent the number negative three quarter.
Point C is 1 mark to the left of 0. This would represent the number negative one quarter.
Point D is 1 mark to the left of 1. This would represent the number positive three quarter.
Point B representing 1 mark to the right of negative 1 is the answer as it is equal to negative three quarter.
100 / 60 = 1.666666666666667
51 x 1.666666666666667 = 85.
The answer is 85%
