Final answer:
To make a decimal into a whole number, multiply it by a power of 10 to move the decimal point to the right until there are no decimal places.
Step-by-step explanation:
To make a decimal into a whole number, we can use multiplication. The number of decimal places in the original decimal tells us how many decimal places to move the digits to the left when multiplying. We can multiply the decimal by a power of 10 to move the decimal point to the right until we have a whole number.
For example:
a. 34.5 × 10 = 345 (moved 1 decimal place)
b. 46.008 × 1000 = 46008 (moved 3 decimal places)
c. 0.23 × 100 = 23 (moved 2 decimal places)
