We have a whole right over here, and then we have 80% more than that. Something that is more than a whole, and then we see that. That is larger than 100%, you're talking about So what percent is representedīy the shaded area? Well, we have 100%, and then Along with Stepwise Solutions, Timing, PDF download to boost your the GCSE Maths Grades. Questions: 1) Convert the following fractions into percentages. Must Practice GCSE (9-1) Maths Fractions to percentages Past Paper Questions. Is the same thing as 80%, so this right over here is 80%. Fractions and Percentages are just two different ways of showing the same value. So four times 20 is 80, so 4/5, or 80/100, is filled out here. So 4/5, if I wanted to express it as per 100, what would it be? Well, five time 20 is 100, In a whole, so that is 100%, and then over here, we have shaded in one, two, three, 4/5 of the whole. What percentage is representedīy the shaded area? Again, pause the video. Whole, so this is a whole, and then this whole thing right Here we are told each large rectangle below represents one The same thing as 30%, which literally means Six per 20 is the same thing as 30 per 100, which is The numerator by five, I'll get the same value. To go from 20 to 100, I multiply by five, and so if I multiply So 6/20, could we write that as per 100? Well, let's see. Squares, we see that six of them are actually shaded in. It as a fraction first, so we have a total of one, What percentage is representedīy the shaded area? So pause the video and see if It says the large rectangleīelow represents one whole. And then we have anotherġ00% right over here, so the whole tape diagram, Well, one way to think about 100%, 100% is equivalent to a whole,Īnd now we have three times as much as that for theĮntire tape diagram, so you could view this as three wholes, or you could say that's 100%. Percent is represented by the entire tape diagram, so by this entire thing right over here. Quiz: Changing Percents, Decimals, and Fractions, and Important Equivalents. Right over here is 100%, and then they ask us what Here, we're told 100% is shown on the following tape diagram, so just this amount "That's the same thing asħ0 per 100, which is 70%." Let's do another example. And once you do more and more percents, you'll get a hang of it. And how did I go from 7/10 to 70 over 100? Well, I just multiply both the numerator and the denominator by 10. You see it cents or century,Īnd so can we write this as per 100 instead of per 10? Well, seven per 10 is the same So one way to think about it is 7/10 are shaded in, but how do we express thisįraction as a percent? They're asking for a percent. Nine, 10 equal sections, of which one, two, three, four, five, six, seven are actually filled in. One, two, three, four, five, six, seven, eight, Percent is represented by the shaded area, so whyĭon't you pause this video and see if you can figure that out. So we're told the square below represents one whole, so this entire square is a whole.
