umm yea...
I tried solving it but I couldn't do it
[18 * (1/2 - 1/9) + 9 / (2/3 - 1/6)] / 2.5
thanks for your help guys i really appreciate it
Answered by Damon
1/2 - 1/9 = 9/18 -2/18 = 7/18
18 * 7/18 = 7

2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2
9 * 1/2 = 9/2

so
7+9/2 = 14/2+9/2 = 23/2
then
23/2 / (5/2) = 23/5 = 4 3/5

The answer here is wrong
this looks hard :(
Answered by bobpursley
parenthesis first
(1/2 - 1/9) and (2/3 - 1/6) or
(9/18-2/18) and (4/6-1/6) or
7/18 and 1/2 . Put those in the problem

[18 *7/18 + 9 / (1/2)] / 2.5

or
((7+9/.5 )/2.5 or
(7+18)/2.5 can you take it from here?

So 25 / 2.5 = 10
