Answer: b. four fifths plus two fourths
Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.
Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.
4/5 <em>20/5 = 4 4×4 = 16 so 4/5 is equivalent to 16/20</em>
2/4 <em>20/4 = 5 5×2 = 10 so 2/4 is equivalent to 10/20 </em>
Add: 16/20 + 10/20 = 26/20
