If you were given the area of a figure and told that all the dimensions of the figure would be cut in half, how could you find the area of the new similar figure? Multiply the area of the original figure by . Divide the area of the original figure by . Multiply the area of the original figure by 4. Divide the area of the original figure by 4.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
