4 1/2 kg + (5 × 0,25) kg
= 4 1/2 kg + (5 × 25/100) kg
= 4 1/2 kg + 125/100 kg
= 9/2 kg + 125/100 kg
= 450/100 kg + 125/100 kg
= 575/100 kg
= 23/4 kg
= 5 3/4 kg
= 5,75 kg

[tex]4 \ \frac{1}{2} + 5 \times 0.25 \\ \frac{9}{2} + 5 \times \frac{25}{100} \\ \frac{9}{2} + \frac{25}{20} \\ \frac{90}{20} + \frac{25}{20} \\ \frac{115}{20} \\ \frac{23}{4} \\ 5 \ \frac{3}{4} [/tex]
