Question

I need help with these 3 questions. No links, please.

Answer 1

Q9: C.

Since each smaller line counts as 1/5, you can simply start from the point 1 and count 3 times to reach D.

`3*(1)/(5) =(3)/(5)`

Since you started at 1, you can add
`1+(3)/(5) =1(3)/(5)`

Q10: B

We can subtract/ignore 3 from all of them to make things simpler.

Now, we need to find the lowest value to greatest from:

`(5)/(8), (7)/(16) ,(1)/(2)`

In order to compare these, we make the denominators the same (in this case: 16)

`(5)/(8) =(5*2)/(8*2) =(10)/(16)`

`(7)/(16) =(7)/(16)`

`(1)/(2) =(1*8)/(2*8) =(8)/(16)`

Since 7 is the smallest value, followed by 8 and lastly 10,

the smallest to greatest in order would be

`(7)/(16) ,(1)/(2) ,(5)/(8)` (B)

11: C

If you look at both
`(2)/(4)` and
`(5)/(8)`, they are not directly above one another. Hence, they are not equal.
