Question

Becky spent 2/3 of her piano practice time on her recital piece. If she spent 25 min. on other pieces, how many hours did Becky spend practicing?​

Answer 1

Answer:

Becky spend 1.25 hours in piano practicing.

Step-by-step explanation:

Let us assume that Becky spends x hours in practicing piano.

If she spent $\frac{2}{3}$ of her piano practice time on her recital piece.  

Then she spent $\frac{2x}{3}$ hours on her recital piece.

So, she spent $(x- \frac{2x}{3} )= \frac{x}{3}$ hours on other pieces.

Now, given that $\frac{x}{3} =25$

⇒ x = 75 minutes = 1.25 hours

Therefore, Becky spend 1.25 hours in piano practicing. (Answer)
