Question

what number should be added to (1/4+1/3) to get 2/3​

Answer 1

Answer:

no is 1 /12

Step-by-step explanation:

let the no be x

$\frac{1}{4} + \frac{1}{3} + x = \frac{2}{3 } \\ \frac{3 + 4 + 12x }{12} = \frac{2}{3} \\ \frac{7 + 12x}{12} = \frac{2}{3} \\ 21 + 36x = 24 \\ 36x = 24 - 21 \\ x = \frac{3}{36} \\ x = \frac{1}{12}$

$21 + 36x = 24 \\ 36x = 24 - 21 \\ 36x = 3 \\ x = \frac{ 3}{36} \\ x = \frac{1}{12}$

Answer 2

Step-by-step explanation:

1/4+1/3+x = 2/3

3+4+12x /12 = 2/3

3+4+12x = 2×12/3

3+4+12x = 8

12x = 8-3-4

12x = 1

x = 1/12
