Which is greater 3.75 3.750

Answers

Answer:

None

Step-by-step explanation:

They are the same number

They are equal and neither is greater than the other.

In the decimal number system, trailing zeros after the decimal point do not affect the value of the number. They are considered insignificant and are not used to determine the magnitude or comparison of the numbers.

When comparing 3.75 and 3.750, it's important to understand that they represent the same value. The digits after the decimal point in both numbers are identical. The presence of the trailing zeros in 3.750 does not change the actual value of the number; it's just a different representation.

To illustrate this, let's consider the number line:

3.749  <  3.7499  <  3.74999  <  3.75  =  3.750  <  3.7501  <  3.75001  <  3.751

As you can see, both 3.75 and 3.750 lie at the same point on the number line, indicating that they are equal in value. The trailing zeros in 3.750 are insignificant and do not affect the magnitude or comparison of the numbers.

Therefore, in terms of their numerical value, 3.75 and 3.750 are equivalent and not different from each other.

Step-by-step explanation:

Monthly salary is $1,750 plus commission for every car he sells.

If he sells 1 car, then his monthly income is $2,250

This means his commission for every car sold is 2250 - 1750 = $500

Thus M = 500n + 1,750

To confirm lets substitute 5 as n.

M = (500 x 5) + 1750

M = 2500 + 1750

M = $4,250

This matches the answer found in the table.
