170 and 30 go into all multiples of their lowest common multiple:
lcm(30, 170) = 510
→ 170 and 30 go into all the multiples of 510, namely:

30% off of 170= 30% discount applied to 170= 170 - (30% * 170)= 170 - 51= 119
Well, isn't that a happy little math problem we have here! To find out what number 51 is 170 percent of, we can set up a simple equation. We divide 51 by 1.70 (which is 170 percent as a decimal) to find that the number is 30. Keep on painting those beautiful mathematical equations, my friend!
In a question like this, the number after the word "of" goes on the bottom (denominator) and the number after "is" goes on top (numerator), forming a fraction. Divide the top number by the bottom number, as 51 divided by 170=.30. That equals 30 percent when you multiply .30 by 100 and move the decimal point two places to the right (one place for each zero in 100.)
170/15 as a mixed number = 11.333333333333334
30% of 170 = 30% * 170 = 0.3 * 170 = 51

If the number is A then 3A + 10(A + 4) = 170 3A + 10A + 40 = 170 13A + 40 = 170 13A = 170 - 40 = 130 13A/13 = 130/13 A = 10 Check: 30 + 10(10 + 4) = 30 + 100 + 40 = 170
