Answer:
5 packages of biscuits and 9 packages of bread.
Explanation:
18x5 = 90, and 9 x 10 = 90. If we use the least common denominator, then it would look like this:
18, 36, 54, 72, 90, 108, 126, 144, 162, 180
10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
Out of the two multiplication lines, the one common part about it would be 90, which is 5 away from the start for 18, and 9 away from the start for 10.
