How is multiplying two decimals like multiplying a whole number and a decimal?
There is almost no difference. The only difference is placing the decimal point.
How is multiplying integers is like multiplying whole number?
In every possible way- because whole numbers and integers are the same.
When multiplying a decimal by a decimal why do you get a smaller decimal?
You only get a smaller decimal if you do 0. something because your multiplying it by 0! oust like with the whole numbers, if you times something by 0 it gets smaller. only with a decimal, there's are still numbers less than the 0 so it gets smaller and smaller until you have a total of 0!
Why do multiples of 10 end in 0?
It is like that because multiplying any number by 10 is the same as adding a 0 at the end of it, unless it is a decimal number. But decimal numbers are not multiples of 10.
What do you round 1.69 to?
That depends on what you want to round it to, like one decimal place or a whole number, as in the following examples: One decimal place: 1.7 A whole number: 2

Is the product of a fraction that is less than one and any whole number less than or greater than the whole number?
the answer is smaller than the whole number because you're taking a fraction of the second number. it's like multiplying by a decimal.
How is multiplying integers is like multiplying whole number?
In every possible way- because whole numbers and integers are the same.
Are decimal whole number?
Yes, they can be but some of them aren't or have a whole number with a fraction of a number. A decimal that's a whole number can be like 1.0 3.0 68.0 etc. A decimal that's not a whole number can be like 0.3 0.89 0.4 etc. A decimal that includes both a decimal and a fraction of number can be like 9.56 6.3 1.23 etc.
Why is the answer larger when you multiply a whole number by a whole number and smaller when you multiply a whole number by a proper fraction?
It is larger because the two whole numbers form a greater, larger number when multiplpied together. It is smaller when u multiply a whole number by a fraction because a fraction is a decimal and u get a smaller number when multiplying a number like 1/7 of 5
How do you align decimals when multiplying?
You do not need to align decimal points when multipylng. You multiply the two numbers ignoring the decimal point but ensuring that any trailins 0s are present. The number of digits after the decimal point in the answer is the sum of the number of digits after the decimal points in the two multiplicands.
How do you divide a whole number by a decimal?
Change the number to a whole number. Like if the problem was 12.128/0.032 you would change it to 12.128/0.032 The answer would easily be 379 because I changed 0.032 to just 32 and then divided it

How is multiplying fractions by a whole number is different from adding adding and subtracting fractions with like denominators?
Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
