Answer:
14 balls will be pink out of 21 balls.
Step-by-step explanation:
Given that:
2 out of every 3 balls are pink in a multi color package.
Ratio of pink balls to balls drawn = 2:3
Number of balls in package = 21 balls
Number of pink balls = x
Ratio = x:21
This is a proportional relationship
2 : 3 :: x : 21
Product of mean = Product of extreme
3x = 21*2
3x = 42
Dividing both sides by 3
Hence,
14 balls will be pink out of 21 balls.
Answer:
Step-by-step explanation:
- The original expression
can be transformed into
: both expressions are equivalent, the root of certain number is equivalent to that number power at a fraction whose denominator is the index of the root. The simpliest example for this statement is
(the squared root of x equals x raised at 1/2).
- Now, the expression
and
. In this case, then
, which is the final expression.
