GuIDED PRACTICE:
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%
