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
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 :(
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
No problem, I'm here to help you! Let's break down the expression step by step:
Step 1: Simplify the expression within the brackets.
Inside the brackets, we have two fractions: (1/2 - 1/9) and (2/3 - 1/6).
To subtract fractions, they need to have the same denominator. The lowest common denominator for 2 and 9 is 18. So, we need to convert the fractions:
(1/2 - 1/9) = (9/18 - 2/18) = 7/18
(2/3 - 1/6) = (4/6 - 1/6) = 3/6 = 1/2
Our simplified expression within the brackets is:
(7/18 + 9/(1/2))
Step 2: Simplify the expression further.
To add fractions, they need to have the same denominator. The lowest common denominator for 18 and 2 is 36. So, we need to convert the fractions:
7/18 = (7/18) * (2/2) = 14/36
9/(1/2) = 9 * 2 = 18
Our simplified expression within the brackets is now:
(14/36 + 18)
Step 3: Solve the expression within the brackets.
To add fractions, we need to add the numerators and keep the denominator the same. So:
(14/36 + 18) = 14/36 + (18 * 36/36) = 14/36 + 648/36 = 662/36
Our expression within the brackets simplifies to:
662/36
Step 4: Divide the expression by 2.5.
To divide a fraction by a number, we multiply the fraction by the reciprocal of that number (the reciprocal of 2.5 is 1/2.5 or 2/5):
(662/36) * (2/5) = (662 * 2) / (36 * 5) = 1324/180
This is our final answer: 1324/180
We can further simplify this fraction by dividing the numerator and denominator by their greatest common divisor, which is 4:
1324/180 = (1324/4) / (180/4) = 331/45
So, the final answer to the expression is 331/45.
I hope this helps!
