Mathapproximation with fractions:7th grade math

How do you find the greater fraction with approximation?
14. 5/12, 17/30
I know that you need to make 5/12 = 6/12 and 17/30 = 15/30
Then compare them to half or something? I'm confused?! Any clear help and instructions?
There are hundreds of ways to make greater fractions. I don't know what approximation means here...the teacher must have given some instruction.
5/12 a greater fraction is 5/11
5/12 a greater fraction is 11/24. (5/12 is the same as 10/24, so 11/24 is greater. However, 10/23 is greater also.
There are many more ways of finding a fraction that is greater then some given fraction. Exact instructions must have come from the teacher on the technique desired. The way to make any fraction greater is to increase the numerator, or decrease the denominator.
Example
95/100 greater would be 191/200 or,
greater would be 96/100, or
greater would be 95/99
Approximating
Multiply 5/12 by 2.5 ahd you have 12.5/30.
Clearly, 17/30 is greater that 12.5/30
12/5 = 2.4
30/17 = 1.76
Clearly, 17/30 is greater than 12.5/30 as its reciprocal is smaller than that of 17/0.
use approximation to tell which fraction is greater the fractions are five twelths and seventeen thirtyoths which one is bigger

15/56 and 8/35

i need help 2

15/56

9/16 21/40 is the answer of 21/40

in 2001, 32 out of 80 members of New Jerseys House of representatives were democrasts and 25 out of 60 members of oregons house of representatives were democrasts. for each state, write a fraction for the number of democrats in the house to the total number of house members.write state had a greater fraction of democrats in its house of representatives?

How do i solve a problem such as .................... 5/24,9/35

Okay im sooo confused NONE of these answers are helping me ! Im doing Math approximations too and here 1 of my problems:15/56 and 8/35 it says use appoximations to get your answer!

ok so here is my ? 19/37 and 24/45 and none of these are helping me i may be a sixth grader but this is getting me really caught up

oh i think i have that same ? i have this paper that a teacher gave me ugggh its sooooooooo HARD!!!!!!!!!!!!!!!!!!!!!

thats what you do if you want to now How do you find the greater fraction with approximation?

yeah this is sooooo hard, does anyone understand? I got to do this for problems 14.19. Its 7th grade math work page 4.5 Anyone got the same?
