+1438 of the 800 participants in a marathon, 120 are running to raise money for a cause. How many participants out of 100 are running for a cause?
+72 Let's start by making a proportion 120/800=x/100, we can simplify 120/800 into 15/100. By doing this 15/100 = x/100. This makes it really easy for us, so there are 15 people running for the cause out of 100.
+343 800 -> 120
100 -> x
800/100 = 120/x
8 = 120/x
x = 120/8
x= 15
15 of 100 run for a cause
Or 15% run for a cause!
I hope I helped you!
+997 Okay...
Are we trying to solve this problem using proportions? Because if so, here is the answer...
\(800 : 120 = 100 : x\),
\(100(120) = 800x\),
\(800x = 12000\)
\(x = 15\).
So, if this question is using proportions to find the number of participants our of 100, the answer would be \(\boxed {15}\).
