7ab a - b
-------------- - --------------
a^2 - b^2 a + b

  7ab a - b
= -------------- - --------------
(a-b)(a+b) a + b

7ab   (a - b)^2
= -------------- - -----------------------
  (a-b)(a+b) (a + b)(a-b)

7ab a^2 - 2ab + b^2
= -------------- - -----------------------
  (a-b)(a+b) (a + b)(a-b)

7ab - a^2 + 2ab - b^2
= -----------------------------------
   (a-b)(a+b)

- a^2 + 9ab -  b^2
= -----------------------------------
   (a-b)(a+b)

A shop sells chocolate, vanilla and strawberry ice creams. 45% of the ice creams sold are vanilla, and 1/4 are strawberry. What

Alinara [238K]

Answer:

Step-by-step explanation:

Total percentage = 100%

And we know that proportions of Vanilla +chocolate +strawberry = 100%

Proportion of Vanilla = 45%

Proportion of Strawberry = 1/4 *100 = 25%

Let proportion of chocolate be represented by variable C;

So, 45% +25% + C = 100%

65% +C = 100%

Subtract 65% from both sides to solve for C;

C=100% - 65%

C = 35%

Therefore there is 35% of chocolate in the shop.
