Answer:
thank you very much ............
If you simplify 24/40:
divide by 4
6/10
divide by 2
3/5
simplify 5/10:
divide by 2
1/5
therefore, 24/40 = 3/5 and 5/10 = 1/5 so 24/40 is 2/5 greater than 5/10
Problem 1
Answers: Choice A, choice D
The formula you use is
a & c/d = (a*d+c)/d
To convert from mixed number form to improper fraction form.
So,
6 & 2/3 = (6*3+2)/3 = (18+2)/3 = 20/3
And also,
8 & 1/5 = (8*5+1)/5 = (40+1)/5 = 41/5

Problem 2
Answer: Reflection
Think of how mirrors cause a reflection and this should help you remember the term better. If we reflect point A over some line L, to get point A', then the distance from A to L is the same from A' to L also.
