Hmm they're both even numbers so maybe we can start by cutting each number in half.

18 and 48 had 2 as a common factor.
So factoring a 2 out of each number was the same as cutting each number in half. Try to do something similar with the 9 and 24. They each have something in common.
100x = 75.757575...
- x = 0.757575...
-----------------------------
99x = 75
x = 75/99
x = 25/33
Answer: 0.757575... = 25/33
Answer:
Step-by-step explanation:
so we are gonna have a percent decrease because it went from 188 to 42
decrease = (original number - new number) / (original number ) * 100
= (188 - 42) / (188) * 100
= (146 / 188) * 100
= 0.7766 * 100
= 77.66% decrease....not sure if u need ur answer rounded to the nearest percent or not....if so, its a 78% decrease
That would be "c" because you would have to subtract 85 from 120 and then your answer is less then 85
