Question

(24+e)÷3=30
820:4-f=148
600-60+g=60
h-640÷2=507
i+707÷7=416
j+999÷9=902
dau coroană​

Answer 1

Răspuns:

Explicație pas cu pas:

(24 + e) : 3 = 30

24 + e = 30 × 3

24 + e = 90

e = 90 - 24

e = 66

Verific:    ( 24+66) : 3 = 90 : 3 = 30

____________________________

820 : 4 - f = 148

205 - f = 148

f = 205 - 148

f = 57

Verificare:    820 : 4 - 57 = 205 - 57 = 148

________________________________

600 - 60 + g = 60

540 + g = 60

g = 60 - 540

g = - 480

Exercițiu corect era:

600 : 60 + g = 60

10 + g = 60

g = 60 - 10

g = 50

_____________

h - 640 : 2 = 507

h - 320 = 507

h = 507 + 320

h = 827

_____________

i + 707 : 7 = 416

i + 101 = 416

i = 416 - 101

i = 315

______________

j + 999 : 9 = 902

j + 111 = 902

j = 902 - 111

j = 791

Verific:  791 + 999 : 9 = 791 + 111 = 902
