Always: 1/(x +1 ) is smaller than 1/x
No, because there is an infinite number of possibilities smaller from the larger gives
The LCM of a set of numbers can never be smaller than the largest number in the set.
You bet. As long as at least one of the factors is a proper fraction. 1/2 x 6 = 3 (product is smaller than one factor) 1/3 x 1/4 = 1/12 (product is smaller than both factors)
YES
no
No
No, 19 is prime and if you ever have a prime number in a fraction, the fraction can not be further simplified (reduced).
Yes, there are times when you multiply fractions.
No, but the chances are smaller when it is cold out.
Yes it does: whenever you find an equivalent fraction.
No.
i don't think so because the mixed number should come out larger the the proper fraction, unless your just looking at the fraction.
