Answer 2

Answer:

1-((15/65)+(48/65))

1-(15/65+48/65)...... since denominator is same we can add both of them

1-63/65.....taking LCM of 1 and 65=65

= 65/65-63/65

= 2/65

0.030769230

ALTERNATIVE METHOD,

1-((15/65))+((48/65))

=1-(3/13)+(48/65)

=1-(0.2307692307+0.7384615384)

=1-0.9692307691

=0.030769230
