Question

help for my holiday home wark

Answer 1

Q1= no of hours=6
      no of hours in a day =24
 
fraction=6/24=1/4
Q2 no of min=45min
      no of min in one hour=60

     fraction =45/60=3/4
Q3 natural no =2,3,4,5,6,7,8,9,10,11.12
  prime no=2,3,5,7,11
total no of prime=5 
total no natural no=11
fraction=5/11

Answer 2

Ans a) 1 day = 24 hours 

            No. of hours  = 6 



$\frac{6}{24 }$ = $\frac{1}{4}$ 

So the final answer is $\frac{1}{4}$ 

The fraction get simplified by 6.


b) 1 hour = 60 minutes 

  No. of minutes   = 45 min


$\frac{45}{60}$ = $\frac{9}{12}$ = $\frac{3}{4}$

First it get simplified by 5 and then 3.



No. from 2 to 12 = 2,3,4,5,6,7,8,9,10,11,12

Prime no. between 2 to 12 = 2, 3, 5, 7, 11

Total prime no. = 5 

Total natural no. = 11 


Fraction = $\frac{5}{11}$

It cannot be simplified hence this is the answer !


Prime numbers = The numbers who don't have any factor except 1 are called prime no.
