Chapter 4 - Decimals - 4.5 Dividing Decimal Numbers - 4.5 Exercises: 32

Answer

$\approx \$0.92$

Work Step by Step

We see that 4 notepads cost $\$3.69$. To find out how much one would cost, we divide: $~~~0.922$ $4\overline{)3.690}$ $~~~~\underline{36}$ $~~~~~~~~~9$ $~~~~~~~~~\underline{8}$ $~~~~~~~~~~10$ $~~~~~~~~~~~\underline{8}$ $~~~~~~~~~~~~2$ We can stop the division with the remainder of 2 because we only need to round to the nearest cent ($\$0.01$): $0.922\approx \$0.92$
