Answer 1

Tutorial on Ratios: I have seen this a lot on other questions and thought, why not make a tutorial about it.

Answer 2

Let's show an example, Trista had 95 correct out of 100 problems on her math test. Write The Percent, Ratio, and written in fraction form.

Answer 3

Ratio-the relation between two similar magnitudes with respect to the number of times the first contains the second: the ratio of 5 to 2, written 5:2 or 5/2. proportional relation; rate: the ratio between acceptances and rejections. How do you find the percent- 1. How to calculate the percentage of a number. Use the percentage formula: P% * X = Y 2.Convert the problem to an equation using the percentage formula: P% * X = Y. 3.P is 10%, X is 150, so the equation is 10% * 150 = Y. 4.Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10. How do you write a fraction from a ratio-To convert a fraction to a ratio, first write down the numerator, or top number. Second, write a colon. Thirdly, write down the denominator, or bottom number. For example, the fraction 1/6 can be written as the ratio 1:6.

Answer 4

The ratio of correct answers to total problems is 95:100. Written in fraction form, this is 95/100. Written as a percent, Trista got 95% of the problems correct.

Answer 5

Let's do one more!, 12 out of 25 students got a B on the weekly math test. The ratio of the number of students out of 25 who did not get a B on the test can be written in three different ways. A.)12 to 25, 12:25, 12/25 B.)25 to 13, 25:13, 25/13 C.)13 to 25, 13:25, 13/25 D.)25 to 12, 25:12, 25/12

Answer 6

So Automatically, You can cross off B, D They are putting the wrong number first.

Answer 7

So Now, It's asking for "How many did not get a B on the test" So Your original is 12:25, You would then take what is missing out of 12:25 which is 13:25.

Answer 8

So The Correct answer would be C.) Due to it being the only one having the ratio 13:25.
