Step-by-step explanation:
26% is the same as 26/100.
The highest common factor of these 2 numbers is 2, so we divide by 2 giving us 13/50.
30% is the same as 30/100. The highest common factor is 10 and when we divide by 10 we get 3/10.
Both of these fractions are less than 1 and so basically, they cannot be mixed number.
