# Thread: What is the equation to this problem if the answer is 42 students?

1. ## What is the equation to this problem if the answer is 42 students? var addthis_config = {"data_track_clickback":false};

Julian found that the ratio of students in his school who had heard of the Egyptian pharaoh Akhenaten to those who hadn't is 7 : 98. If there are 630 students in his school, how many of them had heard of Akhenaten?

2. How many hot college females I'd let butt-bongo my schlong in a single night?

3. Since the ratio is 7 to 98, only 7 out of 105 students have heard of him. (That total is the 7 who have and 98 who haven't.)

S = (7/105) * 630 = 42 students

4. It's the concept of cross multiplication

------------Heard---Didn't---Total
Ratio--------7---------98------105
Students---?---------?-------630

To get number of students who heard of Akhnaton, it's 630*7/105

5. it's just easy
Let x be the missing #
7:98 : x:630
7x630=4410
98x(x)=98x
4410=98x
Divide both side by 98 so the x will be left on the other side. And the answer is:
4410/98=45
98(x)/98=x
So. The missing x is 45 and not 42

6. 7/98,
simplify,
1/14,
total=630,
630/14=45.
