Answer 1

Q. Subtract the sum of -3/7 and 5/28 from the sum of 13/17 and 32/35

Solution:- As per question.

=> [13/17 + 32 /35] - [- 3/7 + 5/28 ]

=> [ (13×35)/(17×35) + (17×32)/(17×35) ]

- [ (-3×4)/(7×4) + 5/28 ]

=> [ 455/595 + 544/595 ]

- [ - 12/28 + 5/28 ]

=> [ ( 455 + 544 )/595 ] - [ (- 12 + 5 )/28 ]

=> [ 999/595 ] - [ - 7/28 ]

=> { 999/595 + 7/28 }

=> { 999/595 + 1/4 }

=> { (4 × 999)/(595×4)

+ ( 595 × 1 )/(595×4) }

=> {3996/2380 + 595/2380}

=> ( 3996 + 595 )/ 2380

=> 4591/2380

=> 1.928991597
