 Concept/Skill Sample YouTube Learn Zillion Khan Academy Breakthrough to Math, Level 2, Book 6 Foundations Mathematics Number Power 6 Breakthrough to Math, Workbook WorkWise: Math at Work Solving single-step word problems with Fractions, Decimals, and Percents For this question: "Jim got a \$0.50 per hour raise and now makes \$13.50. What percent raise did he get?" 1) What question is the problem asking? What percent raise. 2) What facts does the problem give? The raise was \$0.50 per hour. The new wage is \$13.50. 3) Are there any word clues in the problem? 4) What do I need to do to get the answer? We will use the percent statement that the part / whole = percent. The whole is \$13.50. The part is \$0.50. .5 / 13.5 = about 0.04. Then we convert that to a percent by moving the decimal two places to the right. Answer: 4% 4-10 58-60 87-88 115-117 135-136 41-43: Exercises 1-4 Solving Two-step word problems with Fractions, Decimals, and Percents For this question: “Jenny has a family of six.  How much will it cost her to get them all ice cream cones if the cones are 2 for \$2.48?” 1) What question is the problem asking? Cost for 6 ice cream cones. 2) What facts does the problem give? 2 cones cost \$2.48. 3) Are there any word clues in the problem? “2 for \$2.49” tells me I’ll need to divide to find the cost for each cone 4) What do I need to do to get the answer? First, I’ll find the cost for 1 cone: 2.48 / 2 = \$1.24  Then, multiply that cost by the number of family members.  1.24 x 6 = \$7.44 Answer: \$7.44 BUCK system (You do not need to do the Academic Vocabulary part at the end of the video.)
