You could write it as 20/1 but I can think of few things that are as pointless!
11 1/2
12 and 1/2
2 and 1/100
3/2
2 and 3 over 10
2 2/3
change 335/4 to a mixed number
Change them into improper fractions. Invert the second fraction and multiply them together. Reduce if necessary.
Changing mixed numbers percents. First change the mixed number to a decimal then change the decimal to a percent.
To change 18 over 9 to a mixed number, divide the numerator (18) by the denominator (9). The result is 2, which becomes the whole number part of the mixed number. The remainder after dividing is 0, so there are no fractional parts. The mixed number is 2.
4 and 2/12
2 and 1/4
