If you have a calculator: <span>1) To find 1%, divide by 100 (70 / 100 = 0.7) </span>
<span>2) Then, multiply by the % you need (0.7 x 13 = 9.1) </span>
<span>Therefore 70 - 9.1 = 60.9 </span>
<span>If you don't have a calculator: </span> <span>1) Find 50%, 10%, 5%, and 1%. With these, you can make any % you need. </span> <span>50% = X / 2 (= 35) </span> <span>10% = X / 10 (= 7) </span> <span>5% = first, do 10%, then divide that by 2 (= 3.5) </span> <span>1% = X / 100 (= 0.7) </span> <span>Where X is the number you want to work out % for </span>
<span>2) Add those % up to get the amount you want </span> <span>10% + 1% + 1% +1% = 13% </span> <span>7 + 0.7 + 0.7 + 0.7 = 9.1 </span>
<span>Therefore 70 - 9.1 = 60.9 Hope that helps :)</span>
So 9 more than 3 times a number, would be: 9+(3x)=-6 then you would solve subtract 9 from 9 and 9 from -6 you get 3x=-15 divide by 3 on both sides x=-5
