Okay, so i see that you need help with this problem and so 30 percent 1. So 30 goes here of n, so we're looking for the rate is 1.8. So, in order to solve this, whenever you are given the base and the not the rate, but the percentage you're going to do 1.8 times 100 and then divide that by 30- and i got 6 so 6 goes here and n is 6. Then i have 240. Is n percent of 400 point so for this 1 i did 240 divided by 400 and i got 0.6 or 60 percent. Then 2.4 is 30 percent of what number so i'm going to do 2.4 times 100 divided by 30, and i got 8 kay. 225 is 25 percent of what number so i'm going to do 225 times 25 divided by no, that's not what i was supposed to do. 225 times 100 divided by 25, and i got 900 point. Then 70 percent of n is 14.7, so 14.7 times 100 divided by 70, and that's 21 point then, for this next 1113 is 13 percent of what of what number so 113 times 100 divided by 13 point and i did get a decimal. So i'm just going to go out to the tent place. 869.228 percent of n is 1 ud 9…
