Question

Express $\$13$ and $6¢$ as a decimal number in $\$$.

• A. 13.06

Answer 1

The correct option is A 13.06
$\$13$ and $6¢$ means $\$13+6¢$.

Let's convert them into same unit to represent in a single decimal number.

We know that $\$1=100¢$

$\Rightarrow 1¢=\$\frac{1}{100}$
$\Rightarrow 6¢=\$\frac{6}{100}$
$\Rightarrow 6¢=\$0.06$

$\therefore \$13+6¢=\$13+\$0.06=\$13.06$
