Answer:
18/20
Step-by-step explanation:
In order to answer, the denominators need to be the same.
The denominators are 4 and 5. we know that 4 times 5 = 20.
Then, we multiply both numerators by the same number that we multiplied the denominator.
2 times 5 = 10 and 2 times 4 = 8.
Now, we add the new numerators together.
10 + 8 =18
Finally, we "make" the final fraction.
18/20
