Answer: 787/1000
Use a calculator to find that 787/1000 = 0.787 and 7/9 = 0.77777... (the 7s repeat forever)
We see that 0.787 is larger than 0.77777... so that means 787/1000 is larger
You can think of it as 787 is larger than 777 if you move the decimal point 3 spots to the right for each decial value, then round to the nearest whole number.
