1st question : 16,22. 14,20. 12,18
2 is the only number (other than 1, but in most cases 1 does not count) that goes into both 48 and 46.
48 / 2 = 24
46 / 2 = 23
Because of the fact that 48 and 46 are only two numbers apart, it would be impossible for any number greater than two to divide evenly into both.
25 gallons is the correct answer for this on rite here boiii
Solution:
Consider the following expression:
2.5 x 8(20+5)
Solving the expression inside the parentheses first, we obtain:
2.5 x 8(25)
this is equivalent to:
2.5 x 200
this is equivalent to:
500
so that, we can conclude that the correct answer is:
500
