Answer 1

a/b=3/4=k

a=3k

b=4k

b-a=11

4k-3k=11

k=11

a=3×11

a=33

b=4×11

b=44

Answer 2

Salut !

$\frac{a}{b} = \frac{3}{4} = > 4a = 3b$

$b - a = 11 = > b = 11 + a$

$4a = 3(11 + a) = > 4a = 33 + 3a$

$4a - 3a = 33 = > a = 33$

$b = 11 + 33 = 44 = > b = 44$

$verific: \frac{33}{44} = \frac{3}{4}$
