all the numbers have to add up to 100, because those numbers are percents
rebeccaxhawaii (rebeccaxhawaii):
wait how do you know they are percentages?
satellite73 (satellite73):
because it did it the other way and the answer doesn't make any sense
i thought they were the actual numbers, subtracted and got 105 but \(\frac{105}{175}\) doesn't match any answers
that's how
whoever wrote this was not paying attention
satellite73 (satellite73):
you should tell them that if they are using percents, they should spend the ink and put a \(\%\) sign after the numbers
math teachers are not the best some times
rebeccaxhawaii (rebeccaxhawaii):
so the middle is 30%?
