In order to round off to the nearest hundred we have to check the place value on immediate right of the hundred place value. The digit on the right of the hundred is the tens digit. 47 can be written as 047.
The digit on the tens place is 4. So we have to round based on the value of 4.
The rule is if the number on right is 5 or greater than 5, the next digit would be rounded of the next higher digit and the digits on right will be replaced by zeros. If the number is less than 5, the digit will not be changed and all the digits on the right will be replaced by zeros.
In 047, 4 is less than 5. So the first 0 will not change, and the digits on right i.e. 4 and 7 will be replaced by zeros.
So 47 rounded off to the nearest hundred will be 000.
A proportion is a statement that two ratios are equal. A ratio is a comparison of two different quantities. "Miles per hour" is a ratio. "Dollars per pound" is a ratio. A proportion is that two of these things are equal.
For example, paying $2/pound for apples is the same as paying $6 for 3 pounds:
That's a portion.
When working with proportions in word problems, you start by setting up one ratio/fraction where you know all the information. You then set up the second one that's missing a piece of information, but you make sure to set it up using the same structure.
If your first ratio is "miles over hours," then the next ratio has to have the same organization.
If your first ratio is "rise over run," then the next ratio has to have the same organization.
