cross multiply to solve: 100 x 4200 = 87 Y solve for Y by doing 420,000 divided by 87, which equals 4828 (rounded off)
150 (42/0.28) To answer a problem such as this use the formula: a % #/100 = is/of (a % # over '100' b/c the most you can have is 100%) [equation reads, "a percentage number over 100 equals 'is' over 'of'"] So in your case it would be: 1) 28/100 = 42/x (then you cross multiply which gives you): [you have the 'is' as your original question states "is 42." You are trying to find the 'of'] 2) 28x = 4200 (then divide 4200 by 28 to solve for x) x=150 Then to check your answer, plug 150 into the x in the original equation and make sure both sides equal each other. So: 28/100= .28 & 42/150= .28
