# How do I solve 3 1/2r = 28

The solution is, the value of r is 8.

### What is  simplification?

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we get,

given that,

the expression is,

3 1/2r = 28

now, we have to solve the expression to get the value of 'r'.

we get,

3 1/2r=28

7/2r=28

r=(28/1)(2/7)

r=4 × 2

r = 8

Hence, The solution is, the value of r is 8.

How do you compare whole numbers through the millions

Whole numbers are the numbers 0, 1, 2, 3, 4, 5, 6...and so on. It is easier to compare two numbers through the millions using a place value chart. This is illustrated in the Figure bellow. In that example, we have chosen two numbers:

Number one:8,472,102

Number two:8,470,443

So, by comparing these numbers we will have the following steps:

Step 1. The millions are both 8.

Step 2. The hundred thousands are both 4.

Step 3. The ten thousands are both 7.

Step 4. The one thousands digits are 2 and 0.

Stop in this step and compare the digits, so:

2 is greater than 0 or 2 > 0

Therefore, the solution is:

Number one > Number two, that is:

8,472,102 > 8,470,443

In conclusion, you need to stop in the step at which the digits are not the same and compare them. The greatest number is the one with the greatest digit.

A positive number is greater than a negative number. If both numbers are positive, the longer number - the one with more digits - is larger.

The grocery store is having a sale on frozen vegetables. 4 bags are being sold for 11.96. At this rate what is the cost of 1 bag

Answer: \$2.99 (I’m assuming this is money)

Step-by-step explanation: To find the answer you first divide 11.96 by 4. That is because If the there are 4 bags for a total of 11.96 the cost of one bag will go into the total four times.

So 11.96 divided by 4 is 2.99. That means that 2.99 is the cost of one bag because 2.99 multiplied by 4 is the total.

Step-by-step explanation:

The grocery store is having a sale on frozen vegetables. 4 bags are being sold for 11.96. At this rate what is the cost of 1 bag
