Answer:
I don't know. I am so sorry.
1) 26/40 * 15/13
= 2/8 * 3/1
= 6/8
= 3/4
2) 5 and 4/7 ÷ 13/14
= 39/7 * 14/13
= 3/1 * 2/1
= 6/1 or 6

1) 1/5 of 10/11 or 3/4 of 6/7
= 1/1 * 2/11 or 3/2 * 3/7
= 2/11 or 9/14
= 2*14/11*14 or 9*11/14*11
= 28/154 or 99/154
= 28/154 < 99/154

1) no. of children = 40
fraction of children = 1/8 of total passengers
So,
No. of adults = 8/8 - 1/8
= 7/8
If,
1/8 = 40
Then,
7/8 = 40*7
= 280
Therefore, no. of adults = 280
2) Distance car can run in 1Litre of petrol = 17km + 1/2km
= 17km + 1/2 of 1000m
= 17km + 500m
= 17km500m
Simplification of 3litre + 1/5litre:-
= 3litre + 1/5 of 1000ml
= 3litre + 200ml
= 3litre200ml
Distance it will run in 3litre200ml of petrol = 17500*3 + 17500*1/5
= 52500 + 3500
= 56000m
56km
Therefore, it will run 56km in 3litre200ml of petrol.

This is the second last one. I could not solve the last one. Sorry
