Answer:
-0.4=-(2/5)
-----------------------
0.4=0.1+0.1+0.1+0.1
=(1/10)+(1/10)+(1/10)+(1/10)
=(4/10)
=2/5
Therefore, -0.4=-(2/5)
Find the inverse of f(x)=2x-3.
1) replace "f(x)" with "y." Then y=2x-3.
2) interchange x and y. Then x=2y-3. x+3
3) solve this result for y. Then 2y=x+3, or y=----------------
2
-1 -1 x+3
4) replace y with f (x): f (x) = ---------
2
This is the procedure, with the answer given.

Number = 42
50% of 42
= 50/100 × 42
= 21
Increased number = 42 + 21 = 63
