A five digit number with 9 is 99999. A number which is 1000 times larger (not 1000 times as large) is 99999000.
999 + 999/999
One way could be: 999 +9/9 -9/9 +9/9 = 1000
9 x 1000 = 9000
8 x 1 + 5 x 1 over 100 + 9 x 1 over 1000 =[(8 x 1 + 5 x 1) ÷ 100] + [(9 x 1) ÷ 1000] =[(8 + 5 ) ÷ 100] + [(9) ÷ 1000] =[(13 ) ÷ 100] + [(9) ÷ 1000] =[13 ÷ 100] + [9 ÷ 1000] =[13 ÷ 100] + [9 ÷ 1000] =¹³/₁₀₀ + ⁹/₁₀₀₀ =¹³⁰/₁₀₀₀ + ⁹/₁₀₀₀ =¹³⁹/₁₀₀₀ or 0.139
It is 1000 times greater because 1000 times 0.09 = 90
It is: 8 times 125 = 1000
-405
999 + 999/999 = 1000
