6 5. THE STUDENTS ARE CONDUCTING EXPERIMENTS AND THE RESULT IS HOW MUCH THEY HAVE COMPLETED SO FAR. 6. WHO HAS COMPLETED THE MOST OF THEIR EXPERIMENT? 7. WHO HAS COMPLETED THE LEAST? 8. HOW DO YOU KNOW?
7 WHO HAS COMPLETED THE MOST OF THEIR EXPERIMENT? KIM BECAUSE 4/5 = 80% WHO HAS COMPLETED THE LEAST? EDUARDO BECAUSE HE HAS COMPLETED ONLY 60% HOW DO YOU KNOW? BECAUSE I KNOW HOW TO CONVERT AND COMPARE NUMBERS
8 1 3, 3 10, 0.305, 31%, ORDER THESE NUMBERS FROM GREATEST TO LEAST.
9 1 3, 31%, 0.305, 3 10 THESE NUMBERS ARE ORDERED FROM GREATEST TO LEAST. (CONVERT TO DECIMALS AND COMPARE)
