Ratios and Units of Measurement - Step-by-Step Lesson Lesson 1 Ratio Problem: a) How many feet are there in 2 meters? Explanation: Step 1) We know that : 1 m = 3.3 ft Step 2) We have to convert meters to feet by multiplying. 1:3.3 2: x Step 3) Setup the ratio in proportion form:. x Step 4) Solve for x. Cross multiply. 1x = 6.6 x = 6.6 So, 6.6 feet is the same as 2 meters.
Ratios and Units of Measurement - Guided Lesson Complete the following problems: 1) Which is more, 7 centimeters or 60 millimeters? 7 centimeters 60 millimeters Neither, they are equal 2) Convert and simplify your answer. Write it as a proper fraction or as a whole number or mixed number. teaspoons = 3 tablespoons 3) Divide. 40 yards 2 feet 2
Ratios and Units of Measurement - Guided Lesson Explanation Explanation#1 Step 1) The best way to approach this problem is to get all of the measurements into the same unit. Step 2) We know that, 1 centimeter = 10 millimeters Step 3) Now find out how many millimeters are in 7 centimeters. We should multiply 7 x 10 = 70 There are 70 millimeters in 7 centimeters. 70 is more than 60. 7 centimeters 60 millimeters Neither, they are equal So, 7 centimeters is more than 60 millimeters Explanation#2 Step 1) Now we just need to convert one measurement. Step 2) We know that, 1 tablespoon = 3 teaspoons Step 3) We have to find how many teaspoons are in 3 tablespoons. So we have to convert from a larger unit to a smaller unit. Let s get everything into proportion form.
= Step 4) Cross multiply: 1x = 9 X = 9 = 9 teaspoons = 3 tablespoons Explanation#3 Step 1) This is pretty straight forward: 40 yards 2 feet 2 Divide 40 by 2 and 2 by 2. When we divide both the yards and the feet by 2. (40 yards 2 feet) 2 = 20 yards 1 foot So, the answer is 20 yards 1 foot
Ratios and Units of Measurement - Independent Practice Worksheet Complete all the problems. 1) 5 feet 2 inches = inches 2) 8 m 12 cm = cm 3) 7085 g = kg g 4) 2 tons = pounds 5) 6 yards = feet 6) Multiply. 3 times of 5 feet 1 inch = feet inches 7) Divide. 18 tons 42 pounds divided by 3 = tons pounds 8) Multiply. 3 times of 4 yards 2 foot = yards feet 9) Divide. 15 kg 30gm divided by 5 = kg gm 10) Multiply. 24 times 4 tons 2 pounds = tons pounds
