How is a rational number that is not an integer different from a rational number that is an integer

Each integer is rational number, but each rational number is not integer.

Step-by-step explanation:

We are asked to determine how a rational number that is not an integer different from a rational number that is an integer.

We know that an integer is a whole number. It can be positive or negative. We can write any integer as a fraction by writing 1 in denominator. For example 5 is an integer. We can write it as a fraction .

Another example is is an integer.

We know that a number is rational, when it can be written as fraction. For example , but it is not an integer.

Another example is is an integer.

Therefore, each integer is rational number, but each rational number is not integer.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

i think it is 70
