The Basics and Background Information
• A number followed by a percent symbol (%) is equivalent to that number with a denominator of 100 (e.g., 3/5 = 60/100 = 0.60 = 60%).
• A number written in scientific notation is the product of two factors — a decimal greater than or equal to 1 but less than 10, and a power of 10
(e.g., 3.1 × 10^5 = 310,000 and 2.85 x 10^−4 = 0.000285).

Essential Knowledge and Skills
The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to...
7th grade:
• Represent a number in fraction, decimal, and percent forms.
• Compare, order, and determine equivalent relationships among fractions, decimals, and percents. Decimals are limited to the thousandths place, and percents are limited to the tenths place. Ordering is limited to no more than 4 numbers.
8th grade:
• Compare and order no more than five fractions, decimals, percents, and numbers written in scientific notation using positive and negative exponents. Ordering may be in ascending or descending order
