![]() So in August you expect to diagnose approximately $46$ women with depression if the current trend continues. The form of a fraction is $\bigg(\dfrac = 46$ cases, (rounded to the nearest whole number) in August. It's going to be 1.8.Contents Toggle Main Menu 1 Introduction 2 Converting Fractions to Percentages 3 Calculating percentage changes 3.1 Percentage increase: 3.2 Percentage decrease: 3.3 Using percentage change to calculate new amounts: 3.4 Important Note 4 Worked Examples 5 Test Yourself 6 External Resourses IntroductionĪ fraction is a proportion and is usually not a whole number. So if we were to multiplyĠ.30 times 6- let's do that. If you liked this resource, please give my facebook page (where there are many exclusive to facebook resources) a like. And we can verify itĭoing this way as well. Multiply mixed fractions by whole numbers problem solving. Thing as 1.8, which you would have gotten We can divide the numeratorĪnd the denominator by 10. If the percentage you need to convert is not a whole number then multiply both the numerator and denominator by 10 for every number after the decimal point. If you do this multiplicationĬould view this times 6/1- this is equal to 180/100. Or you could view thisĪs 30 hundredths times 6, so 0.30 times 6. This as 30/100 times 6 is the same thing as 30% of 6. So one way of thinkingĪbout 30%- this literally means 30 per 100. So your way to awnser the problem is perfectly okay to use, but I'm just giving you another helpful tip on how to find the answers to these types of problems. Then the last part would be divided each side by 100, which would be 100x divided by 100, and that's x, and 240 divided by 100 which is 2.4!Īs you can see from my explanation and your explanation, they are both trends of simplification. Numbers equal to and larger than 1 are converted to percentages by default and numbers smaller than 1 are multiplied by 100 to convert them to percentages. In order to cross multiply this, you would multiply diagonally, which means would multiply the 100 and the x together which gives you 100x and the 60 and the 4, which gives you 240. If you followed the instructions correctly, you find out that your problem will be like this: 6 would be the of (which would be in the denominator) and the is would be x. The way I would do it is that I would put the 40% in place of the x which would be 40/100, then, as I said a few sentences ago, IS/OF. So, when you said 40% of 6 is 2.4, pretend that we didn't know that 2.4 was the correct answer. Upvote this Job with that formula! I don't know if Sal talked about this, but it's something called is/of = x/100. If you guys want be to talk about the last exercise in khan academy which is called "Finding percents". So our answers to the question "Which of the following options have the same value as 62% of 45" is option c) and a). We literally did it under the phrase I wrote "Lets finish our work." Which one has "0.62 x 45"? option a) does. But there's a faster and better way to go about this.īack when we were answering the question 62% of 45 there was a moment we had the number 0.62. Okay so we 4 more left now we could just enter every question into a calculator to see if it would equal 27.9. Now we need one more answer since the question asks for 2. Now check to see if 60/100 x 45 has the same answer as 27.9. Which option has 62/100 x 45? Option c) does. So lets just solve the equation 62% of 45.Ħ2% = 62/100- WAIT you could stop right here and do 62/100 x 45 instead of converting 62/100 to a decimal. ![]() Now this is just like the first question but asking us what equation is for the correct value of the question "Which of the following options have the same value as 62% of 45?" Which of the following options have the same value as 62% of 45? Chose 2 answers: This question comes from the "Equivalent representations of percent problems" exercise. Now we can get back to the original question What is 1% of 800? What is 1% of 800? (Fact! The "of" in 1% of 800, mean "times" (x) in math, so it really translates: What is 1% x 800?) These question come from the "Benchmark percents" exercise. So this is one of the questions in the exercises you have to do. Im saying this because this has happened before.) (Please don't say I'm getting this off of AI, 'cause im not, I just did some random multiplying and converting and when I put my answer is was correct every time. ![]() Here's what I did so maybe it will help you guys.
