Answer 1

my suggestion is to go on cymath it would help u alot

Answer 2

We have been fractions and we are asked to simplify these fractions. Now let us start one by one.

1)
`3 (1)/(2)+(1)/(8)\\`

Upon changing mix fraction into improper fraction we will get
`(7)/(2)+(1)/(8)\\`

In order to simplify our fraction we need to make our denominators same. To make our denominators same we will multiply our first fraction by 4.

`(7\cdot 4)/(2\cdot 4)+(1)/(8)=(28+1)/(8)\\ =(29)/(8)`

Since are options are mixed fractions we have to convert our answer into mixed fraction.

`=(29)/(8)=3 (5)/(8)`

Option D is correct.

2)
`2 (3)/(4)+5 (3)/(5)\\`

`(11)/(4)+(28)/(5)`

Now we will make both of our denominators same.

`2 (3)/(4)+5(3)/(5)\\ \\ (5\cdot 11)/(5\cdot 4)+(4\cdot 28)/(4\cdot 5)\\ \\ (55)/(20)+(112)/(20)\\`

`(167)/(20)\\ \\ 8 (7)/(20)`

Therefore, correct choice is option (C).

Hope you can use these concepts to answer the rest of the questions :)
