Question

In the division problem 643.43 = 2.5, show how you would change the divisor to a whole number

using powers of ten.

Answer 1

To change the divisor 2.5 to a whole number, you move the decimal point one place to the right, resulting in 25. Then, solve the division problem to find the quotient.

Step-by-step explanation:

When dividing a decimal number by a power of ten, you can convert the divisor to a whole number by moving the decimal point to the right by the same number of places as the power of ten.

1. The division problem given is 643.43 ÷ 2.5.
2. The divisor 2.5 can be written as 25 by moving the decimal point one place to the right.
3. Now, you can solve the division problem: 643.43 ÷ 25 = 25.7372.
