If you think about it, the ratio of 5:2, is basically saying that for every 7 people you have, 5 will be children, and 2 will be adults, or 5/7 : 2/7. So you can set it up as a proportion. If you are looking for the number of children (5 for every 7), you could as 5/7 = x/63000. If you did cross-multiplication (5*63000 = 7*x), you would get that 7x = 315000. If you them divide both sides by 7 to get the variable by itself, you would get that x is equal to 45000. This means that out of the 63000 people in the park, 45000 of them are kids.
You can change the whole number to be an improper fraction depending on the denominator of the fraction.
It is false that <span>x3 + x5 = x8.
In these cases, you don't add the exponents to get the final number. That is the case with multiplication. So, if it said x3 * x5, then the correct result would be x8. But since it is addition, it is not correct. </span>
