Page 6: Warm-up: Write each number below in standard and exponential notation. 1.) 7,000 + 300 + 20 +5 2.) 40,000 + 800 + 60 3.) 90,000 + 700 + 3

Objective: Students will convert decimals to fractions and Objective: Students will convert decimals to fractions and percents.percents.

To convert decimals to percents you multiply a decimal by 100 to find the parts of 100 …. Shortcut …. Move the decimal 2 spaces to the right and add a % symbol.

.82 = 82%

Objective: Students will convert decimals to fractions and Objective: Students will convert decimals to fractions and percents.percents.

Going from % to decimal means dividing by 100….shortcut….replace the % symbol with a decimal and move it 2 places to the left.

Example: 35% = .35

8 % =

235% =
