#2: 4 cans : $2.36 = 13 : $7.67 SCALE FACTOR: $7.67 divided by $2.36 = 3.25 Use the SF to multiply the missing information. So 4 cans x 3.25 = 13 YOU CAN BUY 13 CANS FOR $7.67 #4: 2 eggs: 1 1/2 cups of eggs : 10 pancakes = : : 35 pancakes SCALE FACTOR: 35 pancakes divided by 10 pancakes= 3.5 Use the SF to multiply the missing information So: 2 eggs x 3.5 = 7 7 EGGS WILL BE NEEDED TO MAKE 10 PANCAKES #6: 54 pounds: 1 acre = pounds: 12.5 acres SCALE FACTOR: 12.5 divided by 1 acre= 12.5 Use the SF to find out the mussing information So, 54 pounds x 12.5 = 675 pounds THE FARMER CAN HARVEST 675 POUNDS WITH 12.5 ACRES OF FIELD #8: 90 miles: 120 minutes (5 hours) = 225 miles : 300 minutes (5 hours) SCALE FACTOR: 225 miles divided by 90 miles = 2.5 Use the SF to figure out the missing information So, 120 minutes multiplied by 2.5 = 300 minutes (5 hours) IT WILL TAKE 5 HOURS TO DRIVE 225 MILES
