Reginald answered 78% if the question correctly.what fractional part did he not answer correctly
1 answer:
We are given that Reginald answered = 78% questions.
Total questions in percentage form could be written as 100%.
Reginald answered = 78% so, Reginald answered didn't answer = 100-78 = 12%.
Now, we need to convert 12% into a fraction.
We know, a percentage represents out of 100. So, we need write 100 in the bottom of that number.
Therefore, 12% could be written as 12/100.
Now, we could reduce 12/100 into simplest fraction, by dividing by a common number in top and bottom.
12 and 100 both can be divided by 4.
Dividing 12 and 100 by 4, we get
Therefore, 3/25 fractional part did he not answer correctly.

R = recycling and reuse industry jobs
w = waste management jobs
we know, those two jobs combined are 1,275,000
or
r + w = 1,275,000
we also know that, whatever the "w" jobs are, are really less than "r"
jobs by 1,025,000
"r" has 1,025,000 more than "w"
or
r = w + 1,025,000
or
r-w = 1,025,000
so... there, just solve by elimination, simple, notice the "w",
is just waiting to be eliminated :)
