8–5 Problem-Solving Investigation:Use BenchmarksEXAMPLEMAIN IDEA• Solve problems usingbenchmarks.Solve. Use a benchmark.COOKIES You need 200 grams of flour to make cookies, butall you have is a balance. It doesn’t have any calibrationsto show mass. You do have a package of rice that youknow is 794 grams. How can you measure the flour?UNDERSTAND You need to measure grams of flourusing a balance and a package of rice that isPLANgrams.A benchmark is a measurement by whichother items can be measured. Since thepackage of rice is about 800 grams and youneed to measure 200 grams, divide the riceintoequal portions. Each portionCopyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc.HOMEWORKASSIGNMENTPage(s):Exercises:SOLVEwill be aboutgrams. Use oneportion of the rice to measure an amount offlour with the same mass.Balance one portion of the rice and a cup offlour. Since you know one portion of rice is about200 grams, adjustuntil the two are balanced.CHECK Since 800 ÷ 4 = , you know that eachof the four portions of rice is aboutgrams. By balancing one portion of rice withthe flour, you know the rice and flour areequal. Therefore, you have 200 grams of flourfor the cookies.Check Your Progress Solve. Use a benchmark.COOKING You need 2 1_ cups of water for a casserole, but all4you have is an empty 8-ounce soup can. Describe a way you canmeasure the water.Math Connects, Course 1 207
