Step: 1

The multiplication process ignores the decimal points in the multiplicand and multiplier i.e., 56.3 × 0.5 equals 2815.

After multiplication, count the number of decimal places in the decimal number: 56.3 has 1 decimal place, and 0.5 has 1 decimal place.

Place the decimal point in the product as follows: 28.15.

$1a$

Explanation:

Multiplying decimal numbers, count the total decimal places in the original numbers. In this example, if you multiply 56.3 (which has 1 decimal place) by 0.5 (which also has 1 decimal place), the result will have a total of 2 decimal places. Therefore, \$56.3 × 0.5\$ = \$28.15\$.
