Respuesta :

When adding fractions all denominators must be the same. You multiple 2/3 by 4 so it becomes 8/12 and the same with the others. The answer is 19/12

Answer:

Leah's mistake was that she did not change the numerators

the correct value is 19/12

the Step-by-step explanation:

(2/3) + (1/2) + (5/12)

= (2*2/3*2) + (1*3/2*3) + (5/12)

= (4/6) + (3/6) + (5/12)

= (7/6) + (5/12)

= (7*2/6*2) + (5/12)

= (14/12) + (5/12)

= (19/12)
