The key here is knowing your percent formula, which is 𝘗=𝘉𝘹𝘙. You know that the rate is 65% and the base is 170. So plug in your two figures and then solve for the portion.
FYI, you first need to convert the rate into either a decimal or a fraction first. To convert a percent into a fraction, you divide the number by 100. And to make it a decimal, you'd do this division, which moves the decimal point two places to the left.
70 percent of 170 is 119.
100% - 170% = -0.3% * * * * * Surely, 100% - 170% = -70%
170
170% of 36 is 61.2
.30 x 170 = 51 wrong
170 - 70 = 100
You already have 100% of it, and you want 70% more. You want to end up with 170% of it, so multiply it by 1.7 .
15% of 170= 15% * 170= 0.15 * 170= 25.5
170 = 17,000%
153 / 170 = 0.9 = 90 percent
170 * .35 = 59.50 (35 percent of 170) soooo.... Total is this... 170-59.50=110.50
170% means 170/100 = 1.7 1.7 * 230 = 391
