GED Texas Math Practice test 1 Question and answer rated A+ people can paint a building in 5 days. If each person paints as quickly as the others then how much of the building could 7 people paint in 5 days? 10 people can paint a building in 5 days. Each person paints 1/10 of the building in 5 days. In 5 days 7 people would paint 7 × 1/10 of the building In 5 days 7 people would paint 7/10 of the building. How many meters are there in 21 feet? 3.25 feet = 1 meter 1 foot = 1÷3.25 meters 21 feet = 21×1÷3.25 = 6.4615 meters What is the x value such that y =15 - 3x and y = 0? y =15 - 3x and y = 0 Hence 15 - 3x = 0 Hence 3x = 15 x = 5 Put these four fractions in order from smallest to largest: 1/4, 2/3, 4/7, 1/2 If 1/4, 2/3, 4/7, 1/2 are converted to decimals we get 0.25, 0.6666...., 0.571....., 0.5 then the correct order is obvious or If 1/4, 2/3, 4/7, 1/2 are converted to fractions with a common denominator 21/84, 56/84, 48/84, 42/84 then the correct order is obvious. On a number line what is the distance between -3/7 and -2/3 ? The distance between numbers can be found by using absolute values (|a| or abs(a)). The distance between these numbers is abs(-3/7 − -2/3 ) = abs(-(3/7 -2/3)) = abs(3/7 -2/3) = abs(9/21 - 14/21) = abs(-5/21 ) =5/21
