Question

Calcule:

43% de 800
50% de 96
25% de 300
80% de 470
94% de 70​

Answer 1

OLÁÁÁ!

a). R: 344

100% = 800

43% = x

100x = 43 . 800

100x = 34,400

34,400/100 = 344

b). R: 48

100% = 96

50% = x

100x = 50 . 96

100x = 4,800

4,800/100 = 48

c). R: 75

100% = 300

25% = x

100x = 25 . 300

100x = 7,500

7,500/ 100 = 75

d). R: 376

100% = 470

80% = x

100x = 80 . 470

100x = 37,600

37,600/ 100 = 376

e). R: 65,8

100% = 70

94% = x

100x = 94 . 70

100x = 6,580

6,580/ 100 = 65,8

Answer 2

Resposta:

Explicação passo-a-passo:

i) 43% de 800 = 0,43 x 800 = 344

ii) 50% de 96 = 0,50 x 96 = 48

iii) 25% de 300 = 0,25 x 300 = 75

iv) 80% de 470 = 0,80 x 470 = 376

v) 94% de 70 = 0,94 x 70 = 65,80
