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)

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.
