Question

Solve negative two-thirds times a plus two-fifths equals three-fourths for a.

Answer 1

\[-\frac{ 2 }{ 3 }a+\frac{ 2 }{ 5 }=\frac{ 3 }{ 4 }\]

Answer 2

Is that it?

Answer 3

yes

Answer 4

Ok you need to eliminate all the denominators by finding the LCM of all the denominators you have. The LCM between 3 and 4 and 5 is 60. There is no lower number that all 3 go into. So you multiply each term by 60, like this:

Answer 5

\[(60)-\frac{ 2 }{ 3 }+(60)\frac{ 2 }{ 5 }=(60)\frac{ 3 }{ 4 }\]

Answer 6

It will be easier to do it like this.
