Aling Tina sold 7/9 of her bibingka.If she had 28 bibingka left,how many bibingka she had at first?


Sagot :

If Tina sold 7/9 of bibingka, therefore 2/9 is left.

7/9 + 2/9 = 9/9 or 1 whole or total number of bibingka

Let x be the whole or total number of bibingka.

2/9 of the whole is 28

Equation:

[tex] \frac{2}{9} (x) = 28[/tex]

[tex]( \frac{9}{2})( \frac{2}{9})x = 28 ( \frac{9}{2} )[/tex]

x = (14) (9)

x = 126 

There were 126 bibingka.
