Q. How is the expanded form of the following number written as a decimal?\newline×(1/10)+8×(1/100)+3×(1/1000)78,318,000.00180.783 \begin{array}{l} \times(1 / 10)+8 \times(1 / 100)+3 \times(1 / 1000) \\ 78,3 \\ 18,000 \\ .0018 \\ 0.783 \end{array} \newlineWhich of the following numbers is equivalent to
  1. Calculate 8×(1//100)8\times(1//100): Next, we calculate 8×(1//100)8\times(1//100) which is 8100=0.08\frac{8}{100} = 0.08
  2. Calculate 3×(1//1000)3\times(1//1000): Then, we calculate 3×(1//1000)3\times(1//1000) which is 31000=0.003\frac{3}{1000} = 0.003
  3. Add decimal values: Now, we add up all the decimal values we found: 0.7+0.08+0.0030.7 + 0.08 + 0.003. Adding these together gives us 0.7830.783
  4. Compare with options: We compare the result with the given options.\newlineThe number 0.7830.783 matches with the option 78.3%78.3\%, which is the decimal form of the expanded number.
