$${\mathtt{80}}{\mathtt{\,\times\,}}{\mathtt{0.36}} = {\frac{{\mathtt{144}}}{{\mathtt{5}}}} = {\mathtt{28.8}}$$
If we round up it would be. 36 is 29% of 80.
$${\mathtt{65}}{\mathtt{\,\small\textbf+\,}}{\mathtt{11}}{\mathtt{\,\times\,}}\left({\mathtt{70}}\right) = {\mathtt{835}}$$
Simple as that. Just input 70 in place of n.
If you chose to use a calculator it is quite simple.
$${\mathtt{0.3}}{\mathtt{\,\times\,}}{\mathtt{500}} = {\mathtt{150}}$$
Thus 30% of 500 is 150.
I am studing for my ACT test and these are one of the easist questions to get right if you know the formula.
sqrt((x-x)^2+(y-y)^2
you just input the numbers into the given spaces, but this is how it would look on //web2.0calc.com
If they tell you how many adults are in attendance it only is a matter of minusing the amount of adults by the amount of total people in attendance.
400-136=264
There are 264 students in attendance.
