Answer 1

There are 10 teachers in total.

Step-by-step explanation:

Percent of teachers who gave homework = 20%

Number of teachers who did not give homework = 8

Let,

x be the total number of teachers.

Percent of teachers who did not give home work = (100-20)% = 80%

Therefore;

80% of x = 8

$\frac{80}{100}x=8\\0.8x=8$

Dividing both sides by 0.8

$\frac{0.8x}{0.8}=\frac{8}{0.8}\\x=10$

There are 10 teachers in total.
