Question

Find the quotient: 0.21 ÷ 7 = ___. Explain how the strategy you use to solve this problem relates to a strategy you would use to solve a problem with only whole numbers.

Answer 1

The answer would be .03. How I solved the problem is I moved the decimal of .21 two places to the right resulting in 3. Then I moved the decimal back after getting the answer resulting in .03

Answer 2

The quotient of the expression 0.21 ÷ 7 will be 0.3

The quotient of an expression simply means the division of the numbers that are given. In this case, we'll have to divide 0.21 by 7.

This will then be 0.21/7 = 0.3. Also, in order to solve this, the person can move the decimal place forward twice. This will be: = 21/700 = 0.3

Therefore, the quotient of the expression 0.21 ÷ 7 will be 0.3
