Since (pi) is an irrational number and you can never write it down exactly, you
need something that's close that you can use whenever you need to use (pi).
The closer approximation you use in place of (pi), the closer your answer will be
to the exact truth.
22/7 is a very handy number to use where you need (pi). It's easy to handle, and if you
use 22/7, then your answer is only about 0.04% wrong, which is darn good accuracy.
divide both by 5 35/5 = 7 110/5 = 22 35/110 = 7/22
22 / 7 x 90 = 282.85714
No, it is rational. A rational number is one which can be expressed as a ratio between two integers. Since 22 and 7 are both integers, then 22 over 7 is rational.
3 1/7
Pi has over two billion digits but you can use 3.14 or if you need a fraction 22/7
22/7 = 3 1/7
No. Is you were to convert them into number you will see the difference. the 22/7 it means: 7/7 = 1 21/7 = 3 22/7 = 3.14... And the 7/22 means 22/22 = 1 7/22 = 0.31818...
22/7 × 6/1 = 132/7 or 186/7
22/7 = 3.1428571429 approx= 314%
divide both by 5 35/5 = 7 110/5 = 22 35/110 = 7/22
22/7 is closer
Divide 7 into 22. You will get 3.142857 142857 recurring
7/22 is already in its simplest form
22 / 7 x 90 = 282.85714
22/7 ÷ 7.5 = 44/105
the answer is 22 to 7 or 22:7
You can only express this exactly by leaving it as is: 22/7 times pi. If you want a decimal approximation, use an approximation of pi, for example. 3.1416, and do the calculation on a calculator.
