Question

Will someone explain to me how to solve 1/2+1/4=1/x?

Answer 1

if you multiply both sides by 4

what do you end up with?

Answer 2

Do you mean find the least common multiple?

Answer 3

well... that's another way. yes

Answer 4

I have to explain how I get to the end answer, And I am stuck after cross multiplying...

Answer 5

\(\bf \cfrac{1}{2}+\cfrac{1}{4}=\cfrac{1}{x}\qquad {\color{brown}{ \times 4x}}
\\ \quad \\
{\color{brown}{ \cancel{ 4 }x\times }}\cfrac{1}{\cancel{ 2 }}+{\color{brown}{ \cancel{ 4 }x\times }}\cfrac{1}{\cancel{ 4 }}={\color{brown}{ 4\cancel{ x }\times }}\cfrac{1}{\cancel{ x }}\implies ?\)

Answer 6

You have to fine a common denominator. In this equation it would be 4x. \[1(2x)/2(2x)+1(x)/4(x)=1(4)/x(4)\]

Answer 7

Does that make sense?
