Marco located the falllow points on a number line which point is not corrtly placed on the number line
mario62 [17]

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

Step-by-step explanation:

Given

Point\ A= 0.3

Point\ B= \frac{3}{4}

Point\ C= \frac{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 < \frac{3}{4} < \frac{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.

<em>This implies that point D is not correctly placed</em>

What is the mixed number form of 44/40
crimeas [40]

Answer:

1 1/10

Step-by-step explanation:

44/40

How many times can 40 fit evenly into 44? 1

So 44 - 40 (the 1) = 4

There are 4 remaining which will be the numerator.

The denominator stays the same: 40.

Your answer should look like: 1 4/40

Now simplify: 1 1/10
