7 7 6 14 2 Drill Problems Problems 6 -1, 6 - 3 & 6 - 5, page 157 Convert decimals to percents 8) Problem 6-1 .74 = 74% 9) Problem 6-3 .9 = 90% 10) Problem 6-5 3.561 = 356.1% 11) Solution for Problem #10 When going from a percent, 2.0035% , to a decimal the decimal point is moved two places to the left, thus the decimal equivalent to 2.0035% is .020035 . Now let's count the decimal places to the right of the decimal, we have 10th's, hundredth's, thousandth's, ten thousandth's, one hundred thousandth's and millions. The million position is the "5" in our decimal and becomes our denominator 20,035 1,000,000 This number must be reduced to lowest terms. both the numerator, 20,035 and the denominator of 1,000,000 can be divided by 5, thus your final answer, the correct answer, is 4,007 200,000 Please let me know if you need further explanation: 12) Solution for Problem #12 The initial problem is 2x + 4x = 15 3 8 The common denominator is 24. You should set up the problem as follows: 2x + 4x = 15 16x + 12x = 360 3 8 1 24 24 24 This is what I did. From the original equation up and to the left, I divided the denominator of the first fraction (3) into the new common denominator of 24. My answer of 8 was then multiplied by the numerator of the first fraction (2x) and I got 16x. The same procedure is repeated for the next fraction and the number on the right side of the equal sign. The following is where we are at this point.
