Explicação passo-a-passo:
1Kg = 1000g
1000 ÷ 5 = 200
200 × 4 = 800
4/5 kg = 800g
1000g ----- R$ 10,00
800g ----- X
X= 800×10÷1000
X= 8
1Kg = 1000g
1000 ÷ 5 = 200
200 × 1 = 200g
1000g ----- R$2,00
200g ----- X
X= 200 × 2 ÷ 1000
X= 0,40
8 + 0,40= 8,40
1000g ----- 2,20
200g ----- X
X= 200×2,20÷1000
X= 4,40÷1000
X= 0,44
8,40 - 0,44 = 7,96
800g ----- 7,96
1000g ---- X
X= 1000 × 7,96 ÷ 800
X=7960 ÷ 800
X=9,95
R$ 9,95
