1) To convert 2 1/4 to an improper fraction, we first need to find the equivalent fraction by adding the whole number and the fraction:
2 1/4 = 9/4
To convert to a mixed fraction, we divide the numerator by the denominator and write the quotient as the whole number, and the remainder over the original denominator as the fractional part:
9/4 = 2 + 1/4
So 2 1/4 as a improper fraction is 9/4, and as a mixed fraction it is 2 1/4.
2) As an improper fraction, 21/4 is 21 divided by 4, which equals 5 with a remainder of 1. Therefore, 21/4 as an improper fraction is:
21/4 = 5 1/4
As a mixed fraction, 21/4 can be written as:
21/4 = 5 + 1/4
Therefore, 21/4 as a mixed fraction is:
21/4 = 5 1/4
