Question

what number should be added to 1/2 +1/3 + 1/5 to get 4 ??​

Answer 1

Answer:

the number is

$\frac{89}{30}$

Step-by-step explanation:

given

$\frac{1}{2} + \frac{1}{3} + \frac{1}{5}$

we have to find the number which should be added to get 4

let the number be x

we have addition the number with the equation to get 4

now we get

$\frac{1}{2} + \frac{1}{3} + \frac{1}{5} + x = 4 \\ = x = 4 - ( \frac{1}{2} + \frac{1}{3} + \frac{1}{5}) \\ = x = 4 - ( \frac{15 + 10 + 6}{30} ) \\ = x = 4 - \frac{31}{30} = \frac{120 - 31}{30 } = \frac{89}{30 }$

the required number is

$\frac{89}{30}$
