Answer to Problem 4QC

  $5.2$

Explanation of Solution

Given information:

  $9.4-4.2$

Calculation:

Here we are given with $-$ operator, so we must perform subtraction for the given numbers.

The subtraction operation has been performed below for the given numbers-

  $\underset{\_}{\begin{array}{l}\underset{\_}{\begin{array}{l}9.4\\ -4.2\end{array}}\\ 5.2\end{array}}$

First, we will subtract numbers after the decimal basis their position, subtracting 2 from 4 will result in 2.

Now we will add numbers before decimal, subtracting 4 from 9 will yield 5.

So, the final answer is $5.2$
