Try it out! Do the division! If you get an integer (there are no decimals), it means it is a multiple.
Among the whole numbers alone, 10 is a multiple of 1, 2, 5, and 10. It's also a multiple of an infinite number of fractions and decimals.
No. To be a multiple of 7, the number has to be completely divisible by 7 (no decimals or fractions). However, 48/7=6 6/7 or 6.858... Hence, 48 is NOT a multiple of 7.
Yes - if you do an integer division, you get no remainder. If you divide with a calculator, you get a whole number - no decimals.
Some numbers cannot be written exactly and their decimals repeat infinitely. The best example is 1/3 written as a decimal. It is 0.33333 going on infinitely. Some have multiple digits that keep repeating.
