Question

solve rational number

4/5*5/8-3/9*6/3+1/8*2/7​

Answer 1

(4/5×5/8) + (-3/9×6/3) + (1/8×2/7)

=> (1/2) + (-2/3) + (7/16)

=> 1/2 - 2/3 + 7/16

LCM of 2, 3 and 16 is 48

1/2 × 24/24 = 24/48

2/3 × 16/16 = 32/48

7/16 × 3/3 = 21/48

=>24/48 - 32/48 + 21/48

=>(24 - 32 + 21)/48

=>13/48

ans: 13/48

hope it helps, let me know if there's any mistake :)))
