Course: H.S. Quantitative Reasoning

 

QR.N.1

Represent quantities in equivalent forms (fractions, decimals, and percentages) to investigate and describe quantitative relationships and solve real-world problems in a variety of contexts. Compare the size of numbers in different forms arising in authentic real-world contexts, such as growth expressed as a fraction versus as a percentage. Interpret the meaning of numbers in different forms, such as the meaning of a fraction or the meaning of a percentage greater than 100 and its validity in a given context. Recognize incorrect or deceptive uses of fractions, decimals, or percentages.

*Use the properties of exponents to transform expressions for exponential functions. (MA.AII.EL.4)

*Use proportional relationships to solve ratio and percent problems with multiple operations, such as the following: simple interest, tax, markups, markdowns, gratuities, commissions, fees, conversions within and across measurement systems, percent increase and decrease, and percent error. (MA.7.C.6)

*This course is a 4th year course in the Indiana sequence. The concepts and skills within the course extend to multiple post-secondary pathways and applications.
