9s + 7 = -11 9s = -18 s = -18/9 s = -2
999 + (999/999) = 1000
It is: 3*9 = 27.
It is: 800/1000 = 4/5
111 of them with a remainder of 1
s = 2
250
4/1000
How about 4*250 = 1000 as one example
1 ns (nanosecond) = 10-9s 1s / 10-9s = 109 109 = 1000 000 000 1 second = 1000 000 000 ns (nanosecond)
If 3 quarters of an inch equals 750 miles, then 1 quarter of an inch equals 250 miles. Therefore, 1 inch would equal 1000 miles.
Ninety nine divided by nine equals eleven
