Determine the percent of each number:
160% of $53.27= 85.22
1) I first took the number 100 because I know that if I have 100, 50, and 10, and 1 percent, I can solve any problem. I chose 100 because it seemed to be the easier number to start off with. I then divided the number into 2 (100÷2) to make 50. Together that makes 150, so I need that 10% more. From the 100, I divided it into 10 (100÷10) and that makes 10! On the money part, I calculated using the same method from the percent side and if you add them together, you get your answer. 160% = $85.22.
The second picture just shows a way I do it, if that's easier for you.
3/4% of 135=
2) From the picture underneath the first one, I had to convert the fraction to make it into a decimal, and then a percentage to make it easier. That would make 3/4 turn into 75%. So for the first picture I just showed how 100 could make 75% by dividing 100 by two to make 50, and then dividing it again to make 25. I did this because 50+25= 75. The calculation would by 75%=101.25.
55 8/10% of 500=
3) For the first picture, I divided 100 by two to make 50. From the 100, I also divided by 10 to make 10. From the 10, i divided by 2 and 10 to make 5 and 0.1. I then multiplied 0.1 (0.1 x 8 = 4) because if you didn't multiply, you would just have 55. I did this so I could find out the numbers to get to 55.8 percent. For the numbers side, all I did was use the same method on the other side to get my answer of 249. So overall, my answer would be 55.8 = 279.
The second picture shows a way kind of like the picture on top of it, but just how I do it. All I do is find out the numbers you usually use (100, 50, 25, 10, 1 percent) and then use the numbers you get to get your answer. The second picture shows how I converted first to get a clearer understanding, and then calculating my answer using mental math.
350% of $10=
4) The top picture shows a T-Chart in which I took the percent (100%) and from that number, I found out what 300 percent was. I just had to multiply 100 x 3 which equals 300. The last step was pretty simple. You just had to divide 100 by 2 to get 50. Again, you use the same method you used on the percent part, and use the method for the money part. In other words, I think you could say that you just had to divide 350 by 10 to get $35. 350% of 10= $35.
0.1% of 5 000=
5) The first picture shows that you have to divide. What I did was find out what 100÷100 and that equaled 1. To find 0.1%, you have to divide 1÷10 and that would equal 0.1%. On the number side, you had to divide 5 000 by 100 to get 50, then divide 10 to get 5. 1% of 5 000= 5.
The second picture is the same thing, but instead of dividing, I multiplied.
2 1/10% of $20 000=
6) Finally for the last question, on the first picture it was basically the same thing as the second picture, except it isn't in T-Chart form.
On the second picture, I just had to start off with 100% and use another 100% to get 200%. I then just divided by 10 to get $2 000 and added the numbers all up! I used the same method for the money side.
*I couldn't find a video... sorry... But I did find a video on another way you could find the percent of a number, just not in the way we do it.
