1.   (7⅗ of 17∕ 19) ∕ 15∕25

 

7 3/5  =   38/3

 

And  "of"  means " multiply"  ......so.....

 

(38/3) * ( 17/ 19)  =   (38/19) * ( 17/3)  =  2 * (17/3)  = 34 / 3

 

And  ( 34/3 ) / ( 15/25)   =    (34/3) * (25/15)  =  170/9  ≈   18.888   [8's repeating ]

 

 

3.     log5 (12.5) +  log5 (2)  =   log (12.5 *  2)  =  log5 25 =  2

 

4.    √-4    is   imaginary

2. An improper fraction is classified as a fraction wherein its numerator is greater than or equal to the denominator. 

 

Ex: 

 

1) 7/4

2) 9/2

3) 6/6

 

etc.
