If the chalkboard is just rectangular we can just use:
(2 x L) + (2 x W)
or
L+L+W+W
L= Length
W= Width
Hey there, 15/16 as a decimal is 0.9375, and all you do is add the 4 to 0.9375 and the decimal will become 4.9375. Therefore, 4 15/16 as a decimal is 4.9375
-64 1/3
disregard the negative sign for the moment...
to turn a mixed number into an improper fraction, take ur whole number (63) and multiply it by ur denominator (3) and u get (64 * 3) = 192....now add that to ur numerator (1) and u get (192 + 1) = 193...now put that over ur original denominator (3) and u get 193/3.....now put ur negative sign back....and u have - 193/3.....simplified form, does not reduce
0.000701 in notation is 7.01 x 10^-4
The number has to be greater than 1 but less than 10. If the number is small then the exponent will be negative. 7.01 is less than 10 and greater than 1. In order to get the number you go to the right 4 times.
I hope this helped
