which is 4/3 and you multiply so:2/3 x 4/3 =8/9So the expression looks like this now:1/2+ 8/9- (4/5 x 5/6)Lets keep on solving the brackets. You do 4 x5 = 205 x6= 30(4/5 x 5/6)= 20/30The expression looks like this:1/2 + 8/9 - 20/30So, you just do the question in the order you are told. You do 1/2 + 8/9 first. You find the LCM of the denominators, which is in this case 18.......
2/3 x 4/3 = 8/9
next bracket: (4/5 x 5/6)
= 20/30
= 2/3
therefore, 1/2 + 8/9 - 2/3
in order to add and subtract fractions the denominators must be the same
1/2 + 8/9
= 2/18 + 16/18
= 18/18
= 1
1 - 2/3
= 3/3 - 2/3
= 1/3
final answer: 1/3
You first got to solve the brackets. You do the reciprocal of 3/4, which is 4/3 and you multiply so:
2/3 x 4/3 =8/9
So the expression looks like this now:
1/2+ 8/9- (4/5 x 5/6)
Lets keep on solving the brackets. You do 4 x5 = 20
5 x6= 30
(4/5 x 5/6)= 20/30
The expression looks like this:
1/2 + 8/9 - 20/30
So, you just do the question in the order you are told. You do 1/2 + 8/9 first. You find the LCM of the denominators, which is in this case 18. So we have:
1/2 + 8/9= ?/18+ ?/18= ?/18
Now you would divide by denominator and multiply by numerator to get the number out of 18. So to get the first fraction, you would do (18 /2 ) x 1 = 9. You do this with every thing, and you would get:
1/2 + 8/9= 9/18 + 16/18= 25/18
The expression looks like this right now:
25/18- 20/30 =?
and this is: 0.7222222222222222222222222 or 13/18
Thats ur anwer :)
