Question

What is the answer to 7f/11 =7/11

Answer 1

7f/11=7/11

Cross-multiply.

(7f)/11=7/11

7f*(11)=(7)*(11)

77f=77

Divide both sides by 77.

77f/77=77/77

f=1

Answer 2

So,

$\frac{7f}{11} = \frac{7}{11}$

Multiply both sides by 11.
$7f = 7$

Divide both sides by 7.
f = 1

Check.
$\frac{7(1)}{11} = \frac{7}{11}$
$\frac{7}{11} = \frac{7}{11}$ This checks.

S = {1}
