Less than because you replaced the dividend (3.25) with a less number (3.00) but kept the divisor (1/2) the same.**ALL THE SAME**3.25 divided by 0.5 325/100 divided by 5/10 325/100 divided by 50/100**3.25 divided by 0.5 = 6.5 or 6 1/2**What does the quotient 6.5 represent?**3.25 divided by 0.5 = 6.5 or 6 1/2**What does the quotient 6.5 represent?

Explain.**Without solving decide whether each set lead to the same**quotient. Explain. Set 1 and Set 3 lead to the same answer. The problems in set 2 do not because the quantities being divided are different in each problem. Hint: Move decimals.**-For problem number one just divide to get 25.**-For number two, move the decimal point to the right 2 spots to get the answer (25). -For problem three, move the decimal to the right 3 times to get 37500 divided by 15 to get 2500.
