Find a rational number between 2 and 21/4 using the method of adding the numbers together and dividing by 2. Write as a mix number

Answer 1

To find a rational number between 2 and 21/4 using the method of adding the numbers together and dividing by 2, you add them together:

2 + 21/4 = 8/4 + 21/4 = 29/4

Now, you divide 29/4 by 2:

(29/4) / 2 = 29/4 * 1/2 = 29/8

The rational number between 2 and 21/4 is 29/8.

To write it as a mixed number, divide the numerator (29) by the denominator (8):

29 ÷ 8 = 3 remainder 5

So, the mixed number form of 29/8 is 3 5/8.
