e. Explain to Reese how to multiply and divide fractions.
To multiply fractions, you simply multiply the numerators (top numbers) together and then multiply the denominators (bottom numbers) together. For example, to multiply 1/3 by 2/5, you would multiply 1 by 2 to get 2 as the new numerator, and you would multiply 3 by 5 to get 15 as the new denominator. Therefore, 1/3 x 2/5 equals 2/15.
To divide fractions, you invert the second fraction (flip it upside down) and then multiply the fractions as if you were multiplying. For example, to divide 1/3 by 2/5, you would invert 2/5 to get 5/2. Then you multiply 1/3 by 5/2, which gives you 5/6. Therefore, 1/3 ÷ 2/5 equals 5/6.
I hope this explanation helps you understand how to multiply and divide fractions, Reese. Let me know if you have any other questions!
