![]() Moby is in the background reading a magazine. Tim is sitting at a table, writing on a piece of paper. Tim, a man, and Moby, a robot, appear on-screen. If you want.Text reads: The Mysteries of Life with Tim & Moby. There's no way you could safely eat it all. TIM: Because there's a lot here more than you could possibly eat, unless you want to make yourself sick. TIM: So, you, um… you gonna eat all this pizza? ![]() TIM: And that’s how you convert a decimal back to a fraction! The fraction, 754-thousandths, simplifies to 377/500. Let’s see… divide top and bottom by 2… that makes 377/500! TIM: If you can simplify, you probably should. TIM: If you had a number like 0.754, or 754-thousandths, you'd put 754 over 1,000.Ī decimal appears, reading, 0.754. TIM: So for instance, here, since it's 83-hundredths, we'll make it 83 over 100. On-screen, the hundredths column is highlighted. TIM: To convert back to a fraction, place the numbers after the decimal point over the whole number value of the last digit’s place. The number, 8, is in the tenths column, and the number, 3, is in the hundredths column. On-screen, the decimal, 0.83, appears in the labeled chart. TIM: We know that because the last digit is in the hundredths place. As I said before, it’s also called 83-hundredths.Īn equation appears, reading, 0.83 equals 83/100. TIM: Oh! What if you want to convert back to fractions? Well, that's easy. TIM: And that's how you convert fractions to decimals. It turns into the fraction, 83-hundredths. TIM: We can round it off at the hundredths place if we like, and say that 5/6 is about 0.83, or 83-hundredths.Ī decimal appears, reading, 0.83. When a decimal repeats a number like that, it's called a…Ī label reading "repeating decimal" appears below the solution. You can calculate it out using long division or with a calculator, if you have one available.Ī long division equation appears, reading 5 divided by 6 equals 0.83, followed by many more 3s. TIM: To write 5/6 as a decimal, we need to calculate 5 divided by 6. TIM: This small pizza, as you can see, has been cut into 6 pieces.Ī fraction appears, reading 6/6. TIM: Right, what about other fractions, like, oh, I don't know… ![]() This method works for all fractions that have a 10, 100, 1,000, or some other power of 10 in their denominator.įractions appear, reading: 9/10 77/100 and 337/1,000. On-screen, an 8 replaces the 0 in the tenths column, immediately to the right of the decimal point. TIM: It's easy to see where the tenths position is… All we have to do is slip our 8 in there. From left to right, the first 3 columns are labeled "hundreds," "tens," and "ones." The middle column is labeled "decimal point." The next 3 columns from left to right are labeled, "tenths," "hundredths," and "thousandths." An arrow points to the "tenths" column. TIM: Now the key thing to know here is the decimal places.Ī chart appears. TIM: Moby's apparently really hungry, and we're left with 8 out of 10 pieces. TIM: So 10 divided by 10 equals the whole number 1.Īn equation appears, reading, 10/10 equals 1. On-screen, the 10 in the fraction's numerator flashes. TIM: And so far there are 10 pieces still here. On-screen, the 10 in the fraction's denominator flashes. TIM: Fractions indicate division, in this case we know that a whole pizza has 10 slices. TIM: This large pizza is cut into 10 slices. Hey, what fantastic luck that's just what I'm doing! Perhaps Moby's pizza can help. TIM: Dear Tim and Moby, can you help me with changing fractions into decimals? From, Samantha. Moby goes to the door and returns with 3 boxes of pizza. Text reads: The Mysteries of Life with Tim and Moby
