Taking into account of the significant figures, what is the value of 9.99m–0.0099m9 . 99m – 0 . 0099m?

Options

  1. A9.98m9 . 98m
  2. B9.980m9 . 980m
  3. C9.9m9 . 9m
  4. D9.9801m9 . 9801m

Correct answer

A. 9.98m9 . 98m

Step-by-step solution

In subtraction the number of decimal places in the result should be equal to the number of decimal places of that term in the operation which contain lesser number of decimal places.

9.99−0.0099\begin{array}{ll}9 .99 \\ - 0 .0099\end{array}9 .98</p><p></p><p>⇒ 3$ siginificant figures
