Question

A number plus two-thirds of itself added to one -half of itself, again added to one-seventh of itself equals 97.Find the number.

Answer 1

Step-by-step explanation:

Let the number be x.

So

x +2/3 x + 1/2 x + 1/7 x = 97

So take the lcm of the denominator.

We get 3*2*7 = 42

(42 x + 28x + 21x + 6x) / 42 = 97

70x + 27x = 97*42

97x = 97*42

x = 42
