91 timesjust do:2/100=502/80=402/2=150+40+1=9191.. without the aid of a calculator !
2 goes into 80 .....40 times
It equals 80.You can also use a calculator.
The formula to figure out the circumference of a circle is C=2(pi)r. So with a circle that has a radius of 40 inches, you can set up the formula like: C=2(pi)40. To figure this out on a calculator, multiply 2 with pi and then multiply that answer with 40. If you do not have a pi symbol on your calculator you can multiply 2 with 3.14159 then multiply that answer with 40.
20 times 2 = 40
40 is the answer
2/5, or two fifths. if you type in 2 divided by 5 on a calculator, it'll say ".4", which is 40%
That number is called the square root of 40. You can calculate a decimal approximation of square roots on any calculator, including the calculator available on Windows.
You could try 80/2
80
Yes. There are numerous ways this could be done, assuming the multiplication and division keys are working. 20 x 2 = 40 8 x 5 = 40 16 x 2.5 80 / 2 = 40 120 / 3 = 40 200 / 5 = 40
