3x/4 - 2x/5 + x/2
So what is to be done?
it is in fraction form & i have to solve i guess.... the mutipul choice answers are as follows in fraction form:
a. x/10
b.3x/10
c.17x/20
d.33x/20
please help me....
go and
find the lowest common denominator between the 4, 5 and 2
a common multiple is 20 so..
3x/4 - 2x/5 +x/2=
5(3x/20)- 4(2x/20) + 10(x/20)=
then multiply ...
15x/20 - 8x/20 + 10x/20=__________ ???
now add and what do you get?
If the equation is:
(3x/4) - (2x/5) + (x/2)
Common denominator is 20
(15x/20) - (8x/20) + (10x/20) =
combine the three to obtain
17x/20
~*THANKS*~
17x+5=-3(4)
To simplify the expression 3x/4 - 2x/5 + x/2, we need to find a common denominator for all the fractions.
The common denominator is the smallest multiple of the denominators of all the fractions, which in this case is 20 because 4, 5, and 2 are all factors of 20.
Now, let's rewrite each fraction with the common denominator:
(3x/4) = (15x/20) (multiplied numerator and denominator by 5)
(2x/5) = (8x/20) (multiplied numerator and denominator by 4)
(x/2) = (10x/20) (multiplied numerator and denominator by 10)
Now, we can combine the fractions by adding the numerators while keeping the common denominator:
(15x/20) - (8x/20) + (10x/20)
To combine the numerators, we subtract the second fraction and add the third fraction:
(15x - 8x + 10x) / 20
Simplifying further:
(17x + 10x) / 20
Finally, we combine the like terms:
27x / 20
So, the simplified expression is 27x/20.
