Answer:  Eric practiced piano for 2 hours this week.

Step-by-step explanation:  Given that Eric practiced piano and guitar for a total of 8 hours this week . He practiced the piano \dfrac{1}{4} of that time.

We are to find the number of hours that Eric practiced the piano this week.

Let, 'h' represents the number of hours that Eric practiced piano this week.

Then, according to the given information, we have

h=\dfrac{1}{4}\times\textup{total number of hours Eric practiced piano and guitar}\\\\\\\Rightarrow h=\dfrac{1}{4}\times 8\\\\\\\Rightarrow h=2~\textup{hours}.

Thus, Eric practiced piano for 2 hours this week.

zysi [14]

Answer:

700

Step-by-step explanation:

For this one I'll do estimates. 271 estimated would drop down to 270. And 425 would bump up to 430. Adding 270 and 400 you would get a round number of 700!

Hope this helped.

2. The ratio of boys to girls in the school
andrew11 [14]
Since the ratio is 3:4, and 12/4 is 3 than you do 3x3 and get 9 so the answer is 9:12 or 9 boys and 12 girls. To check your answer, you can do 3/4 (for 3:4) and that is 0.75. If you do that with 9:12 you also get 0.75.
