What else can I help you with?
How could you use estimation to check the reasonableness of the quotient for 3.99 and 0.84?
4 x 0.8 = 3.2
How do you use estimation to check an answer?
To use estimation to check an answer, first round the numbers involved in the calculation to make them simpler. Then perform the estimated calculation and compare the result to your original answer. If the estimate is significantly different from your original answer, it may indicate that there is an error or that the original answer needs to be re-evaluated. This method helps verify the reasonableness of the final answer.
How can estimating be used to check multiplication?
Estimating can be used to check multiplication by rounding the numbers involved to make the calculation simpler and more manageable. By performing the estimation, you can quickly assess whether the result of the original multiplication falls within a reasonable range. If the actual product is significantly different from the estimated value, it may indicate an error in the multiplication process that needs further investigation. This method serves as a useful tool for verifying calculations efficiently.

How do you check your multiplycation?
To check your multiplication, you can use the inverse operation: division. Divide the product by one of the original factors; if the result equals the other factor, your multiplication is correct. Another method is to break down the multiplication into smaller parts using the distributive property and then add the results. Additionally, you can use estimation to see if the product is reasonable.
