Answer:
70 is what percent of 280?
Explanation:
Percent means per 100. So the example question asks 70 out of 280 is what percent. You can do this problem a couple of different ways.
1. Set up a proportion (two fractions equal to each other,) and solve.
70/280 = x/100
reduce the left side.
7/28 = x/100
reduce further.
1/4 = x/100
cross-multiply.
1(100) = 4x
100 = 4x
divide by 4
100/4 = 4x/4
25 = x
70 is 25% of 280.
OR
you could divide directly and move the decimal two places to the right to find the percent.
70/280
= .25
move the decimal two places to the right.
.25 becomes 25%
I can edit if you actually wanted to see 60 and 300. Hope this helps!
