Answer:
23/10 gallons
Step-by-step explanation:
Alicia uses 3/4 gallon of paint to paint her room.
Alicia use = 3/4 gallon of paint
Becca uses for 4/5 gallon more than Alicia to paint her room.
Becca uses = Alicia (3/4 gallons ) + 4/5
Becca uses = [tex]\frac{3}{4} + \frac{4}{5}[/tex]
Total paint used together = Aliccia used + Becca used
[tex]\frac{3}{4}+\frac{3}{4} + \frac{4}{5}[/tex]
Add like fractions 3/4 + 3/4 becomes 6/4
[tex]\frac{6}{4} + \frac{4}{5}[/tex]
Make the denominators same
[tex]\frac{6*5}{4*5} + \frac{4*4}{5*4}[/tex]
[tex]\frac{30}{20} + \frac{16}{20}[/tex]
[tex]\frac{46}{20}[/tex]
Divide top and bottom by 2
[tex]\frac{23}{10}[/tex] gallons
