MIXED NUMBERS MOVIE TRANSCRIPT

Title text reads, The Mysteries of Life with Tim and Moby. A letter appears. Text reads as Tim narrates:

Dear Tim and Moby,
What is a mixed number?
From,
Dino 11

TIM: Well, a mixed number is made up of a non-0 integer and a fraction. 1 and one-half; 2 and three-quarters; 27 and three-eighths. These are all examples of mixed numbers.

On-screen, three mixed numbers appear: 1 and one-half; 2 and three-quarters; and 27 and three-eighths.

TIM: Moby and I are working with a mixed number right now.

Moby beeps.

TIM: We're supposed to add 2 and a half liters of oil to the car. 2 and a half really means 2 plus one-half.

On-screen, 3 bottles of oil appear. 2 of the bottles are full, and the third is half-full. The mixed number, 2 and one-half, appears.

TIM: Converting a mixed number to a fraction is just a matter of adding 2 fractions.

Moby beeps.

TIM: Well, look at 2 and a half. To add 2 and one-half, we need to write 2 as a fraction with a denominator of 2. Two is the same thing as 4 halves.

On-screen, 2 circles split in half, creating 4 half-circles. The fraction, four-halves, appears.

TIM: Now adding them together is easy. Four-halves plus one-half equals five-halves.

On-screen, 1 half-circle joins4 half-circles, creating a total of 5 half-circles. An equation appears, reading, four-halves plus one-half equals five-halves.

TIM: A fraction like five-halves with the numerator larger than the denominator is called an improper fraction.

A label appears, reading, improper fraction. Moby covers his mouth and beeps.

TIM: No, they're just called that.

Moby smiles and beeps.

TIM: Oh! There's a shortcut for converting mixed numbers to fractions.

Moby beeps.

TIM: Yeah... um... how much oil do we have left over?

Moby beeps

TIM: 3 and three-quarters liters of oil.

On-screen, 4 bottles of oil appear. 3 of the bottles are full, and 1 is three-quarters full.

TIM: The shortcut is to multiply the whole number by the fraction's denominator, and then add the numerator to the result.

On-screen, the mixed number, 3 and three-quarters, appears. Arrows identify the whole number, 3, the denominator, 4, and the numerator, 3.

TIM: We place that result over the denominator and get our improper fraction. So, 4 times 3; that's 12; plus 3 is 15.

On-screen, the denominator, 4, is multiplied by the numerator, 3, for a product of 12. 12 is then added to the numerator, 3, to create the improper fraction, fifteen-fourths.

TIM: 15 over 4; fifteen-fourths.

On-screen, the bottles of oil are each divided into fourths, labeled, 1 through 15.

TIM: See, Moby? Mixed numbers aren't so tough... Moby?

Moby drinks a bottle of oil and holds a second bottle in his other hand.

TIM: Maybe you should go easy on that stuff.

Moby lets out a robotic burp.
