It's about the science of predictions that says how the world will be in future . Then, there's also Statistics that also shows the way our world is evolving. Thirdly, forecasting has equal importance in doing that, like town population graphs or cow growth rate. All these use graphs and ratios in order to get a visual information about our enquiries, be it in Medicine, Biology, the Earth movement or the Universe.

5 divided by 485 3 digit by 1 digit

victus00 [196]

Answer:

$5\div485=\dfrac{5}{485}=\dfrac{1}{97}\\\\485\div 5=\dfrac{485}{5}=97$

Step-by-step explanation:

When we say "a divided by b", we mean a/b. In this case, "5 divided by 485" is a 1-digit number divided by a 3-digit number. The result is the fraction 1/97 or a repeating decimal with a long repeat.

If you want to divide the 3-digit number 485 by the 1 digit number 5, then you need to formulate the problem as "485 divided by 5". The result is 97.
