Greetings!

Convert both terms into improper fractions:
$=9/1-59/8$
Find the LCM.
$=72/8-59/8$
Simplify.
$=13/8$
Convert to Mixed Number.
$=1 \frac{5}{8}$

The second answer would be correct.

Hope this helps.

Riya took a train from his hometown to Mumbai . The journey lasted for 3 hrs 35 minutes . The train reached the station at 9:15

zhenek [66]

Answer: 5:40 am

Step-by-step explanation:

The train reached the station at 9:15 am after having travelled for 3 hrs 35 minutes.

The time the train departed from Riya's hometown was the time it arrived in Mumbai station less the time taken to travel:

= 9:15 - 3:35

First deduct the 3 hours:

= 9:15 - 3

= 6 : 15 am

Remove the 35 minutes by first removing the 15 minutes

= 6:15 - 15

= 6:00 am

Then remove the rest of the 35 minutes which is 20 minutes:

= 6:00 - 20 minutes

= 5:40 am

Andreas93 [3]

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.

We have given that,

A pool of possible candidates for a student council consists of 14 freshmen and 8 software.

We have to determine the how many different councils consisting of 5 freshmen and 7 sophomores are possible

<h3>What is the combination?</h3>

$_n C_r=\frac{n !}{r ! (n-r) !}_n C_r = number of combinations\\\n = total number of objects in the set\\\r = number of choosing objects from the set$

The total number of the council is

$_{10} C_5\times _9 C_7$

=252(36)

=9216

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.
