PLZ HLP ASAP!!<br> [9(14 + 16) • 2 – (8 • 4 + 12 • 9)] ÷ 40
lara [203]
\frac{9(14+16)*2-(8*4+12*9)}{40} \\&#10;\frac{(9*2)(14+16)-[(8*4)+(12*9)]}{40}\\&#10;\frac{(18*30)-(32+108)}{40}\\&#10;\frac{540-140}{40}\\&#10;\frac{400}{40}\\&#10;10
So the expression is equal to 10.

Iff a/b is a rational number, what does b have to equal in order for a/b to also be an integer
postnew [5]

You're thinking b=1 will always give an integer, certainly true.

Then you think b=-1 will also always give an integer, so

Answer: ±1

Then you remember that a/b may not be a reduced fraction, so other bs beside the unit make give integers.   The condition for an integer is

b | a

read 'b divides a'  meaning a is a multiple of b.

Then you realize that a and b might not even b integers themselves.

Let's say the above answer is correct with the additional criteria that a and b are integers with no common factors.
