What is 22% of 80?
There are a lot of ways you can get to your answer, but..
one way you can find the answer is to...
Step 1 : Find out what 10 % of 80 is.......... the answer is 8.
Step 2 : Do that again, 10% of 80 = 8.
Step 3: Find out what 1% of 80 is .......... it is 0.8
Step 4 : Do that again, 1 % of 80 = 0.8
Step 5 : Add the percentages together ( 10% + 10% + 1% + 1% = 22%)
Step 6: Add the answers together ( 8+8+0.8+0.8 )
The way I first found out my answer was by doing this ( I don't know if this is a correct way of doing it, but I'll just tell you how ) :
Step 1 : Find 25% of 80......You get 20
Step 2 : Find what 1% of 80........ It's 0.8
Step 3 : Again, find what 1% of 80 = 0.8
Step 4 : And again, find what 1% of 80 = 0.8
Step 5 : Add the Percentages, located in the purple "thing". Equals to 3%
Step 6 : Add the decimal numbers in the purple "thing". The answer is 2.4
Step 7 : Do 20 - 2.4 = 17.6, your answer! You're probably thinking where I got 20 from, that was when we did step one.
Step 8 : Lastly, Do 25% - 3% = 22%

Match each sentence beginning in column A to an ending in column B.
1) To represent a percent great than 100%, shade more than one hundred grid.
2) To represent a fractional percent greater than 1, shade squares from a hundred grid to show the whole number and part of one square to show the fraction.
3) To represent a whole percent, shade squares on a grid of 100 squares called a hundred grid.

How many hundred grids are needed to show each of the following percents? Explain your thinking.
9a) For 230%, you would need (3) hundred grids, because (2) hundred grids would be fully colored, and you would still need to color 30%, so 3.
9b) 680% would need (7) hundred grids, you always want to go one grid higher than how much hundreds you have in your number.
9c) 395% ......................... Think about it!................... Your answer, (4) hundred grids.
9d) 1420% Hmm.. Now let's think about that, you would need (15) hundred grids because, like I said in question 9b, " you always want to go one grid higher than how much hundreds you have in your number "
So, in this case, there are 14 hundreds in 1420, so you would go one grid higher, which is 15!
