1000 + 9 = 1009
9/1000 + 3/100 = 39/1000 = .039
987/1000
Its 500,500. you just work 1000 x 1001 divided by 2
whats 9 plus 10 21
6000.......it's actually 5,100
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
4100
500,500
1000+40=1040 1040+1000=2040 2040+30=2070 2070+1000=3070 3070+20=3090 3090+1000=4000 4000+10=4100
1000 + 1000 - 1000 + 1000 = 2000
5+3/10+6/100+9/1000
8030 plus 1799 can be expressed in expanded form as follows: 8030 = 8000 + 30 1799 = 1000 + 700 + 90 + 9 When you add these together in expanded form, it becomes: (8000 + 30) + (1000 + 700 + 90 + 9) = 8000 + 1000 + 700 + 30 + 90 + 9. The total is 9829.
