Rakshak solves problems in maths for 4/7 if an hour.He studies marathi for 5/9 an hour. Does he spend the same amount of time for both the subjects?
Answers
Answer:
No
Step-by-step explanation:
Given,
Time spent by Rakshak for Maths =4/7 of an hr
Time spent by Rakshak for Marathi=5/9 of an hour
1st Method
We can check which fraction is greater
4/7 can be re written as 4×9/7×9 (Multiplying both
numerator and
denominator with 9)
=36/63
5/9 can be re written as 5x7/9×7 (Multiplying both
numerator and
denominator with 7)
=35/63
Here, 36/63>35/63
Therefore 4/7>5/9
Hence,He spends more time for maths
2nd method
1 hour= 60 minutes
Time Rakshak spent for maths=4/7 of 60 minutes
=4/7×60
=240/7
=34.286 minutes
Time Rakshak spent for marathi=5/9 of 60 minutes
=5/9×60
=300/9
=33.333 minutes
Here,34.286>33.333
Hence,He spends more time for maths.
So,he is not spending the same amount of time for both the subjects.
