Answer/Step-by-step explanation:

How can you fluently add, subtract, multiply, and divide decimals?

To add or subtract decimals:

1.Write the numbers vertically with the decimals lined up (if the number is a whole number then the decimal goes on the right end of the number)

2.Add zeros to make sure there are the same number of digits in each number.

3.Add or subtract as normal.

How can you multiply and divide fractions?​

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
