How can I tell if my estimated answer is greater or less than the exact answer to a multiplication problem?
Assuming that the estimate is based on sensible approximations, there is no simple way. You will need to compare the estimate and the true value. If you've rounded up, the estimate will be greater. If you've rounded down, the estimate will be less.
Why is the square root of a fraction greater than the given fraction?
You mean a proper fraction (less than 1). Multiply anything by less than 1 and you will make it smaller. Therefore the square root of your result is bigger than the start value. For numbers bigger than one it's the other way round.
How do you find the variable in greater than and less than equations?
More or less solve it as if the inequality sign was an equals sign. When solving for x, y=mx+b and y<mx+b are done the same way. You just end up with x< or > some number rather than x= some number.
If a is less than b and b is less than c is a greater than c?
Horse Isle Answer: No EXPLANATION: The simplest way to solve is to simply assume numbers to substitute the variables: a=1, b=5, c=13 does this match the first two conditions? yes, it does: 1
What is the minimum perimeter of the rectangle?
The way the rectangle is usually defined, a rectangle has to be positive, so any number greater than zero will do. Note that the set of numbers greater than zero has no minimum.
