Q. What do you mean by inverse relation ? How can I find it out ? ツ

☄ A relation obtained by interchanging the first and second component of each of ordered pair of a given relation R is known as inverse relation of R. It is denoted by \tt{ {R}^{ - 1}}. In other form, if R be a relation from A to V then the relation from B to A is called the inverse relation of R.

Symbolically , if R = { ( x , y ) : x ∈ A , y ∈ B} then \tt{ {R}^{ - 1}} = { ( y , x ) : y ∈ B , x ∈ A }

☏ To be more precise , All you have to do is interchange the first and second component of each of ordered pair of a given relation.

✺ \tt{STUDY \: TIP} :

  • 1 - 3 - 5 Rule : When making a to - do - list , add 1 big , 3 medium and 5 small task to accomplish. If you still have some task left , follow the same pattern. ♪

Answer: 3/4 hours

Step-by-step explanation:

Target hours = 4 1/2 hours = 9/2 hours

Number of hours so far :

(1 1/2 + 1 1/4 + 1) = (3/2 + 5/4 + 1) hours

Total so far :

L. C. M of denominator = 4

(6 + 5 + 4) /4 = 15/4

Number of hours left to meet his target equals :

Target hours - total so far

( 9/2 - 15/4)

L. C. M of denominator = 4

(18 - 15) / 4 = 3/4 hours

.
