At the annual Grade 8 ski trip, for every 2 students who skied, 3 snowboarded. Ninety-six students snowboarded. How many students skied? Show your work. Can someone help???
I'd set it up as a proportion.
2/3 : x/96
Cross multiply and solve for x.
2:3 = x:96
96/3 = 32
2•32 = 64
64 students skied.
Another way to read the problem is this:
3/5 of the students snowboarded. A total of 96 snowboared. How many skied?
Notice the denominator, and how it was calculated.
thanks alot you two i understand it now.
You're welcome.
Why did the scarecrow become a snowboarder? Because he heard it was all downhill from there!
Now, let's figure out the answer to the question! We know that for every 2 students who skied, 3 snowboarded. And we're told that 96 students snowboarded.
To find how many students skied, we'll set up a proportion:
2 students who skied / 3 students who snowboarded = x students who skied / 96 students who snowboarded
Cross-multiplying, we get:
2 * 96 = 3 * x
192 = 3x
Dividing both sides by 3, we find:
x = 64
Therefore, 64 students skied.
To determine how many students skied, we can use the given ratio between students who skied and students who snowboarded.
The ratio states that for every 2 students who skied, 3 students snowboarded.
We know that 96 students snowboarded, so we can set up the following equation:
2/3 = x/96
To solve for x (the number of students who skied), we can cross-multiply:
2 * 96 = 3x
192 = 3x
Divide both sides of the equation by 3:
192/3 = x
64 = x
Therefore, 64 students skied.
