Answer:
4 11/20
Explanation:
We can start by converting all the fractions into improper fractions:
1 4/5= 4/5+5/5=9/5
2 3/20= 40/20+3/20=43/20
This means the equation would be
9/5+(43/20+3/5)=
We now need to get a common denominator.
We can do this by multiplying 9/5 and 3/5 both by 4/4.
This said, 9/5 would become 36/20
and 3/5 would become 12/20
Our equation is now:
36/20+43/20+12/20=
This equals
91/20
which simplifies to
4 11/20
