Answer:
39/50
Step-by-step explanation:
The original expression can be restated as follows:
0.78 = 0.70 + 0.08
Convert:
0.70 = 7/10
0.08 = 8/100
Add 7/10 + 8/100:
7/10 + 8/100
Find least common multiple, which is 100:
=(70+8)/100
=78/100
Now, simplify by dividing by 2 for both top and bottom:
39/50
