Question

5. Using only odd numbers for numerators,

Answer 1

Answer:

• 3/4 - 1/4 = 1/2
• 5/8 - 1/8 = 1/2

Step-by-step explanation:

You can pick just about any fraction with an odd numerator and find another at distance 1/2 from it.

For example, 5/7 - 1/2 = 10/14 - 7/14 = 3/14. So your subtraction problem can be ...

  5/7 - 3/14 = 1/2

Choosing a denominator divisible by 4 can make both parts of the problem use the same denominator.

  3/4 - 2/4 = 1/4, so the corresponding subtraction problem is 3/4 - 1/4 = 1/2.

  5/8 - 4/8 = 1/8, so the subtraction problem is 5/8 -1/8 = 1/2.
