Answer:
This is a greatest common factor problem.
What is the greatest common factor of 18 and 30?
18 is 1 x 18: 2 x 9; 3 x 6
30 is 1 x 30: 2 x 15: 3 x 10; 5 x 6
Our greatest common factor is 6.
How many 6 inch boards can you cut from 18 and 30 inches.
18/6 = 3
30/6 = 5
Or, when you find the GCF, it's multiple is the number of boards at that length that can be cut.

Answer:
Step-by-step explanation:
area = ½(base)(height) = ½(22)(12) = 132 cm²
First off, turn 7 1/4 into a mixed number, 29/4. change 29/4 / 5/6 into a multiplication question by flipping 5/6 into 6/5 (AKA multiplying by the reciprocal) so you get 29/4 X 6/5. then multiply so you get 174/20. Next, simplify into a mixed number by seeing how many times 20 goes into 174, and then putting the leftovers into a fraction, so you get 8 14/20, then simplify even further so you get 8 7/10.
