c ÷ d = 3 rest 3 ⇒ c = 3d + 3
c + d = 75 ⇒ c = 75 - d
75 - d = 3d + 3
72 - d = 3d
72 = 4d
d = 72 ÷ 4
d = 18
c = 75 - 18
c = 57
[tex]\displaystyle{a = \frac{2}{4} \cdot c = \frac{2c}{4}}[/tex]
[tex]\displaystyle{a = \frac{2 \cdot 57}{4}}[/tex]
[tex]\displaystyle{a=\frac{114}{4}}[/tex]
a = 28,5

b = 4 × 6
b = 24
Fie Dif = (a + b + d) - c
Dif = (28,5 + 24 + 18) - 57
Dif = (52,5 + 18) - 57
Dif = 70,5 - 57
Dif = 13,5
