8 0

Answer:

The answer is 4.

Step-by-step explanation:

In order to get this answer you have to use inverse operations. The inverse operation for multiplication is always division. So, you have to solve the equation 7.5 ÷ 1.75. When getting the answer to that (the answer of the equation above), you get n, as it is only a one-step equation. I hope I could help you.

Answer:

1050

Step-by-step explanation:

Natural Numbers are positive whole numbers. They aren't negative, decimals, fractions. We can just divide 5 into 100 to find how many natural numbers go up to 100 and just add them but that is just to much.

There is a easier method.

E.g: Natural Numbers that are divisible by a Nth Number. is the same as adding the Nth Numbers to a multiple of that Nth Term. For example, let say we need to find numbers divisible by 2. We know that 4 is divisible by 2 because 4/2=2. We can add the Nth numbers which is 2 to 4. 4+2=6. And 6 is divisible by 2 because 6/2=3. We can call this a arithmetic series. A series which has a pattern of adding a common difference
