Answer 1

Answer:

If Chitra drinks some water from 8/9 of water and now the bottle is 1/2 full, then she had to drink 7/18 of water.

Step-by-step explanation:

Amount of water in Chitra’s bottle = \frac{8}{9}

9

8

After she drank some of the water from the bottle, amount of water left in the bottle = ½

Let the amount of water she drank be denoted as “x”.

According to the question we can write the equation as,

\frac{8}{9}

9

8

– x = \frac{1}{2}

1

⇒ [8 – 9x] = 9/2

⇒ 16 – 18x = 9

⇒ 18x = 7

⇒ x = \frac{7}{18}

18

7

Thus, Chitra had to drink \frac{7}{18}

18

7

of water from the bottle.
