Hi !
Question no: 7 :-
sum of 3/4 and 7/8
lcm of 4 and 8 = 8
3*2/4*2 = 6/8
6/8 + 7/8 = 13/8
∴ 3/4 + 7/8 = 13/8
sum of 11/13 and 5/26
lcm of 13 and 26 = 26
11*2/13*2 = 22/26
22/26 + 5/26 = 27/26
∴11/13 + 5/26 = 27/26
the qn is to multiply the answers obtained :-
3/18 × 27/26
= 81/468
= 9/52 [ simplest form ]

1/1 - 1350/2106
