2 squared X 5 X 7 squared. 2x2x5x7x7=980 980 is not a prime number
Find the common denominator of the 7 and the 2 which is 14. 5/7 now becomes 10/14 and 1/2 now becomes 7/14. 10/14-7/14=3/14 Find common denominator for 3 and 7 which is 21. 1/3 now becomes 7/21 and 3/7 now becomes 9/21. 7/21+9/21=16/21 final problem is 3/14 X 16/21=48/294 ...
Ms. Sue is correct.
math (comparing ratios)
I think the answer is 48/4 or in simplest form, it is 12/1.
Pretty sure the answer is 1 to 4.
At Chaniel's school, one cafeteria helper is chosen from each class by a random drawing. In Chaniel's class, the probability of the chosen person being taller that five feet is 1/5. Find the odds in favor of the chosen person being taller than five feet.
1/6 possibilities. Numerator stays the same when converting possibilities to odds. Subtract the numerator from the denominator, so 6-1=5. Numerator stays at 1 and denominator is now 5. Pretty sure the answer is 1 to 5. Is this right?
A bag contains five white marbles and one green marble. The marbles are randomly selected one at a time. What are the odds of picking the green marble on the first selection?
Not sure if this is what you're looking for but, they both have four sides.

A cube has 8 vertices. A square pyramid(pyramid with a square base) has 5 vertices. A triangular pyramid (pyramid with a triangular base) has only 4 vertices. A Pyramid has 5 vertices 5 faces and 8 edges and those are all answers for a Pyramid that has a square base on it.
answer is 0
