You can check any multiplication problem by running it back as division. If A x B = C, then B = C/A and A = C/B but that seems like a lot of trouble. If you want to see if you have multiplied two numbers correctly, multiply them again. If the two products match, they're probably correct.

What is a multiplication problem in which the product has two Decimal places?
Well, honey, any multiplication problem where both numbers have decimal places will give you a product with two decimal places. It's as simple as that. Just multiply those numbers together and you'll get your fancy little answer with two decimal spots. Math doesn't have to be a drag, darling, just embrace those decimals and get multiplying!
How can you use inverse operations to check your answer to a decimal addition problem?
If you have calculated A + B = C then you can calculate C - A. If the answer is B then the first sum is correct.
How do you write a fraction as a multiplication problem?
2/3 = 2 x 1/3
What is the estimate when both factors in a multiplication problem are rounded up to estimate the product?
That's an overestimate.
Convert each decimal fraction to binary using repeated-multiplication-by-2?
Well, isn't that just a happy little question! To convert a decimal fraction to binary using repeated multiplication by 2, you can multiply the decimal part by 2 and write down the whole number part of the result. Then, take the decimal part of the result and repeat the process. Keep doing this until the decimal part becomes 0 or until you reach the desired level of precision. Just remember, there are no mistakes, just happy little accidents in the world of math!
