yes
Smaller. The product of any positive number and a number between 0 and 1 will be smaller than the original number.
It is zero. No matter how many times you multiply a zero, it is always zero. 0.
9 times the number
The product is even.
yes
No. The identity for multiplication is the number 1. If you multiply a number by 1, then the product is the original number. If you multiply a number by zero, the product is zero, so the number has 'lost it's identity'
The product would always be 0.
Smaller. The product of any positive number and a number between 0 and 1 will be smaller than the original number.
There is no multiplicative inverse of 0. By definition, when you multiply a number by its multiplicative inverse, the product is 1. However, when you multiply 0 by anything, the product is 0. Those two statements could not logically co-exist if there were any multiplicative inverse of 0, so there is no such thing.
10
It is zero. No matter how many times you multiply a zero, it is always zero. 0.
the answer is 0.5
9 times the number
891 is the largest.
It depends. If you start with a positive number, then multiply by a positive greater than one and the answer is greater; multiply by 1 and the answer is the same; multiply by a number between 0 and 1 and the answer is smaller; multiply by 0 and the answer is 0; multiply by a number less than 0 and the answer is negative.
The product is even.
