r-ruslan [8.4K]

Let x + 15 = total penguins

15/ (x +15) = .30

15 = .30x + 4.5

.30x = 10.5

x = 35

Total penguins = 15 + 35 = 50

Double Check

15 / 50 * 100 = 30% Correct!!!

<u>Answer:</u>

The answer is the same i. e., 4.375 in all the cases as shown below.

<u>Step-by-step explanation:</u>

$\frac {3}{7} \times \frac {5}{6} \times \frac {1}{4}$

= $\frac {35}{8}$

= $\frac {3}{7} \times \frac {1}{4} \times \frac {5}{6}$

= $\frac {5}{6} \times \frac {1}{4} \times \frac {3}{7}$

= $\frac {5}{6} \times \frac {3}{7} \times \frac {1}{4}$

= $\frac {1}{4} \times \frac {5}{6} \times \frac {3}{7}$

= $\frac {1}{4} \times \frac {3}{7} \times {5}{6}$

= 4.375 (answer)
