9 plus 3 over x divided by x over 4 plus 1 over 12 equals ?
1 answer:
Answer:
36/x
Step-by-step explanation:
(9+3/x) / {(x/4)+(1/12)}
{(x/4)+(1/12)} = (3x+1)/12
(9+3/x) = (9x+3)/x
(9+3/x) / (3x+1)/12
(9x+3)/x /(3x+1)/12
((9x+3)/x ) . (12/(3x+1))
12(9x+3) / (x(3x+1)
108x+36 / 3x² + x
36(3x+1) /(x(3x+1)
3x+1 cancels each other
36/x
