fun math
Do you know how to set up proportions?
nope
Alright, I'll try to explain it to you, just give me second.
So, because they are similar, when the sides are divided by one another they should be equal. So, first you start with two fractions: Figure 1: 10/24 Figure 2: x/15 We are going to find the value of x that when divided by 15 equals the same thing as 10/24
If you were to put this on paper, it would look sorta like this: 10 x -- = -- 24 15 First you cross multiply. Can you show me what you get after cross multiplying?
16?
Not quite, 10*15=150 24*x=24x So, we know have the equation: 24x=150 Can you solve the equation?
126?
How did you get 126 for x?
-24 both side
The equation isn't 24+x, it's 24x, which is 24*x. So, to isolate the x in an equation like this, you need to divide it by 24, and to do the same with 150 to keep both sides equal.
6.25
Yes, so now that we have an answer, we can double check it to make sure it works out. 10/24=0.416 6.25/15=0.416 This means that we succeeded in getting the right answer. All that's left to do is simplify the original fraction: 150/24 into the simpler: 25/4 <--- Your Answer
