amplificati cu 5 fractiile 3 supra 4 ,11 supra 10

3/4 = 3×5/4×5 = 15/20
(15 supra 20)

11/10= 11×5/10×5= 55/50
(55 supra 50)

Intai de toate, a aplifica inseamna a inmulti, deci:
[tex] \frac{5}{1} [/tex] * [tex] \frac{3}{4} [/tex] = [tex] \frac{15}{4} [/tex] = 3 [tex] \frac{3}{4} [/tex] = 3,75

[tex] \frac{5}{1} [/tex] * [tex] \frac{11}{10} [/tex] = [tex] \frac{55}{10} [/tex] = 5 [tex] \frac{1}{2} [/tex] = 5,5
