Question

Please help please I’m failing every thing I’m trying to pass

Answer 1

`11(7)/(10)`

Explanation:

`\displaystyle 3(1)/(4)+\biggr(3(1)/(4)+5(1)/(5)\biggr)\\\\3(5)/(20)+3(5)/(20)+5(4)/(20)\\\\(3+3+5)+\biggr((5)/(20)+(5)/(20)+(4)/(20)\biggr)\\\\11+(14)/(20)\\\\11(7)/(10)`

Again, make sure all denominators are the same by using the least common denominator (in this case it's 20 since 5*4=20).
