Roman and ranjan each divided 3.56 by 0.72. roman got 4.94 for his quotient. which student divided correctly? how do you know? explain it! no scaming me > =-(

Let's concentrate on the math, please, and not on "no scamming me."

Any number other than zero, if divided by a number between 0 and 1, results in a larger number.

Thus, 3.56 divided by 0.72 results in a number larger than 3.56.  Thus, at first glance, 4.94 seems quite reasonable as the answer here.

Could you use long division to find the actual quotient?

You could multiply both 3.56 and 0.72 by 100 to get rid of the decimal points.  Then you'd be dividing 72 into 356.

Can you do that on paper?

Can you do that using a calculator?

Is the result equal to 4.94?

You have not shared what result Ranjan got, so it's hard to judge which student got the correct result.  Perhaps both did!
