Every spring, tourists visit the Netherlands to see tulips in bloom. Analyze this scene to answer the math questions.
Testing Proportions
Use the picture to determine if the statements below are true or false using the proportions for the tulip prices listed in euros (€). Record your work and answers on our answer sheet.
TRUE OR FALSE:You will pay 12 euros for 36 red tulips.
TRUE OR FALSE:You will spend 15 euros to buy 75 pink tulips.
TRUE OR FALSE:You will pay the same price to buy 48 yellow tulips as 45 purple tulips.
Ratios are comparisons between two quantities. When two ratios are in proportion, they can be simplified to the same ratio.
Is 20/25 in proportion to 8/10?First, find the greatest common factor (GCF) of 20/25.Factors of 20: 1, 2, 4, 5, 10, 20Factors of 25: 1, 5, 25
Then find the GCF of 8/10.Factors of 8: 1, 2, 4, 8Factors of 10: 1, 2, 5, 10
So the ratios are in proportion. If the simplified fractions were not equal, they would not be in proportion.
