What: converting and Comparing

Fractions, Decimals, and %’s

Why: To convert between fractions and decimals; and to compare fractions, decimals, and percentages.

Today’s lesson . . .

Converting Decimals to Fractions:

Read it, Write it, Reduce it!

Think about decimal

language!

1. 0.05 2. 0.4 3. 0.020

Convert the following decimal #’s into fractions. Remember, if you can say the decimal #’s in your head (using decimal language)– you can write the decimal as a fraction! READ IT, WRITE IT, REDUCE IT!

Continued:

Read it, Write it, Reduce it!

4. 4.03 5. 0.002 6. 5.005

Your TURN:

Comparing Fractions, Decimals, and %’s:

Let’s practice COMPARING a MIXTURE of fractions, decimals, and %’s at the same time. Remember, CONVERT TO DECIMALS FIRST!!!!Guided practice:

STRATEGY: Convert everything into decimals first!

Place a “greater-than” (>), “less-than” (<), or “equal” (=) sign in the blanks:1) 0.023 _____ 0.6 2) 35% _____ 3.5 3) 2/5 _____ 40%

4) 2.5% _____ 5) 0.5 _____ 5% 6) ¼0.75% _____ 0.75

Your turn:Place a “greater-than” (>),“less-than” (<), or “equal” (=) sign in the blanks:1) 4.5 _____ 45% 2) 15% _____ 0.092 3) 3/8 _____ 0.4

4) 6.8% _____ 0.68 5) 20% _____ 1/5 6) 5.09 _____ 450%
