Answer:

red balls = 15

Explanation:

It is given that The ratio of blue balls to red balls is 4: 5.

Let's assume

If there are 27 balls in total it means that sum of Blue balls and red is equal to 27.

Blue balls + red balls = 27.

$:\implies \: \:$ 4x + 5x = 27

$:\implies \: \:$ 9x = 27

$:\implies \: \:$ x = 27/9

$:\implies \: \:$ x = 3

Number of blue balls = 4x

$:\implies \: \:$ 4 × 3

$:\implies \: \:$ 12 balls

Number of red balls = 5x

$:\implies \: \:$ 5 × 3

$:\implies \: \:$ 15 balls.

Verification :

$:\implies \: \:$ Blue balls + red balls = 27.

$:\implies \: \:$ 12 + 15 27

$:\implies \: \:$ 27 = 27

Hence, Verified!

Therefore, The total number of red balls are 15.
