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
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.
To find a rational number between 2 and 21/4 using the method of adding the numbers together and dividing by 2, follow these steps:
1. Add the two numbers together:
2 + 21/4 = 8/4 + 21/4 = 29/4
2. Divide the sum by 2:
(29/4) / 2 = 29/4 * 1/2 = 29/8
To write it as a mixed number, divide the numerator (29) by the denominator (8) and represent the quotient as a whole number part and a fraction:
29 ÷ 8 = 3 remainder 5
The whole number part is 3, and the fraction part is 5/8.
Therefore, the rational number between 2 and 21/4 is 3 5/8.
To find a rational number between 2 and 21/4 using the method of adding the numbers together and dividing by 2, follow these steps:
1. Determine the two numbers between which you want to find a rational number. In this case, the numbers are 2 and 21/4.
2. Add the two numbers together:
2 + 21/4 = 8/4 + 21/4 = 29/4.
3. Divide the sum by 2:
(29/4) / 2 = 29/4 * 1/2 = 29/8.
4. To write the answer as a mixed number, divide the numerator by the denominator. The quotient will be the whole number part, and the remainder will be the numerator for the fractional part.
29 ÷ 8 = 3 remainder 5.
So, the rational number between 2 and 21/4 is: 3 5/8.
