Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\frac{5}{6}

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\boxed{\text{Solving the Problem...}}\\\\2\frac{1}{2}  -\frac{5}{3}\\\\----------------\\\rightarrow \text{LCM} (2,3): 6\\\\\rightarrow 2\frac{1}{2}=\frac{5}{2}=\frac{5*3}{2*3}=\frac{15}{6}\\\\\rightarrow \frac{5}{3}=\frac{5*2}{3*2} =\frac{10}{6}\\\\\\\rightarrow \frac{15}{6} - \frac{10}{6}\\\\\rightarrow \boxed{\frac{5}{6}}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

In a tutoring session, 2/3 of an hour was spent reviewing math problems. Adelina attended 3/4 of the tutoring session. How much
fgiga [73]

Answer:

Time spend by Adelina at the tutoring session is 30 minutes.

Step-by-step explanation:

Given : In a tutoring session, \frac{2}{3} of an hour was spent reviewing math problems and Adelina attended \frac{3}{4} of the tutoring session.

We have to find the time Adelina spend at the tutoring session.

We know, 1 hour = 60 minutes.

Total time taken in tutoring session = \frac{2}{3}\times 60=40 minutes.

also, Adelina attended \frac{3}{4} of the tutoring session that is \frac{3}{4} of 40 minutes.

that is \frac{3}{4}\times 40=30minutes.

Thus, time spend by Adelina at the tutoring session is 30 minutes.
