When multiplying decimals to values like $10, 100, 1000 \dots$ $10, 100, 1000…$ , simply move the decimal point to the right by the number of zeroes.

Since the decimal is being multiplied by $10$ $10$ , simply move the decimal point $1$ $1$ place to the right.

Therefore, $0.74 \times 10$ $0.74xx10$ is equal to $7.4$ $7.4$

First, ignore the decimal points of the two values and multiply them

$1.7$ $1.7$ $=$ $=$ $17$ $17$

$40 \times 17$ $40xx17$ $=$ $=$ $680$ $680$

Next, count how many place values from the decimal point to the right of the two factors.

$1.7 =$ $1.7 =$ $1 place$ $1 \text(place)$

There is a total of $1$ $1$ place value movement to the right of the decimal point.

Finally, get the final product by moving the decimal point of the initial product $1$ $1$ place to the left.

Therefore, the final product is $68$ $68$ .

First, ignore the decimal points of the two values and multiply them

$0.5$ $0.5$ $=$ $=$ $5$ $5$

$0.6$ $0.6$ $=$ $=$ $6$ $6$

$5 \times 6$ $5xx6$ $=$ $=$ $30$ $30$

Next, count how many place values from the decimal point to the right of the two factors.

$0.5 =$ $0.5 =$ $1 place$ $1 \text(place)$

$0.6 =$ $0.6 =$ $1 place$ $1 \text(place)$

There are a total of $2$ $2$ place value movements to the right of the decimal point.

Finally, get the final product by moving the decimal point of the initial product $2$ $2$ places to the left.

Therefore, the final product is $0.3$ $0.3$ .
