Question

Divide 54 into two parts such that one part is 2/7 of the other.

Answer 1

2/7*x=54
x=54*7/2
x=189

Answer 2

Dear Student,
Solution:

Let we assume the one part to be 'x':
then the other party will become....
$\frac{2}{7} \times x = \frac{2}{7} x$
Now..
•According to Question:
$x + \frac{2}{7} x = 54$
$7x + \frac{2x}{7} = 54$

$\frac{9x}{7} = 54$
$9x = 378$
$x = \frac{378}{9}$
$x = 42$

Now, we can say that if one part is 42, then the other part will be....

$\frac{2}{7} x = \frac{2}{7} \times 42 = 2 \times 6 = 12$
•Hence, the two parts are 42 and 12.
