Given ratio: 5 (goats) : (to) 8 (sheep.)
The question asked that if Giles had 32 sheep, then how many goats would he have. We can figure out how many goats he would have by cross multiplying fractions.
5 z
- x -
8 32
To figure out the z variable, we simply cross multiply 5 and 32, which gets us 160. Now we divide it by 8. Whatever we get for z, that is our answer for goats. The answer would be <span>20.

To solve x in the equation <span>x2 = 64, we raise the whole equation to the reciprocal of the power of the variable present which means we raise it to a power of 1/2. 64 raised to 1/2 or square root of 64 is equal to positive 8 and negative 8. The solution set is {-8,8}</span>
