5. Verify the property a× (b-c)= a×b-a×c for each of the following:
a= -3\5; b= 5\9; c= -10\3

We conclude that

        L.H.S = R.H.S    

Step-by-step explanation:

Given the property expression

Given that:

Determining the LEFT-HAND SIDE

substituting a= -3/5, b= 5/9 and c= -10/3

Determining the RIGHT-HAND SIDE              

substituting a= -3/5, b= 5/9 and c= -10/3

Apply the fraction rule:  

Therefore, we conclude that

        L.H.S = R.H.S                                          

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
