So firstly, multiply both sides by 4 (the reciprocal of 1/4): 
Next, subtract both sides by 2 and your answer will be: 
Answer:
The numbers less that 40 which have sum of digits 8 are 17, 26, 35.
Only one of those that has a factor of 7. And that is 35.
So you are 35.
Second way:
The numbers less that 40 which have a factor of 7 are 7,14,21,28,35
Only one of those which has sum of digits as 8. And that is 35.
So you are 35.
Step-by-step explanation:
In total there are 20 students and only 6 read 1 book. So the answer would be 6/20
110 x 10 - 4 x 7
1,100 - 28
1,072
Since I don't see attachment, I guess the solution will be as follows:
1 & 3/4 , since 1 = 4/4, then it could be rewritten :
4/4 & 3/4, hence between these 2 fraction there is 2/4 or 1/2.
