Question

Marco located the falllow points on a number line which point is not corrtly placed on the number line

Answer 1

Question:

Marco plotted the following 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:

Point D

Explanation:

Given

`Point\ A= 0.3`

`Point\ B= (3)/(4)`

`Point\ C= (11)/(4)`

`Point\ D= 0.7`

Required

The incorrectly plotted point

Number plotted on a number line increases from left to right. This implies that:

`A < B < C < D`

Substitute the values for the given points

`0.3 < (3)/(4) < (11)/(4) < 0.7`

Express as fractions

`0.3 < 0.75 < 2.75 < 0.7`

Up till 2.75, the order of the numbers is correct.

However, 0.7 is less than 0.75 and 2.75

So, 0.7 is not placed correctly.

This implies that point D is not correctly placed
