Answer:
20 3/4
Step-by-step explanation:
First, add together the whole numbers:
5 + 15
= 20
Then, add the fractions and decimals together:
Convert 1/4 to a decimal, which is 0.25
Add the decimals together:
0.25 + 0.5
= 0.75
Convert this to a fraction:
0.75 = 3/4
Then, add together 20 and 3/4
20 + 3/4
= 20 3/4
