Question

1*2*3*a=24 a=
b*2*5=40 b=
27:3:3*d=6*4 d=
c:2:3=5 C=
e:8+2000=2003 e=

Answer 1

Explicație pas cu pas:

1 × 2 × 3 × a = 24

6 × a = 24

a = 24 : 6

a = 4

_____

b × 2 × 5 = 40

b × 10 = 40

b = 40 : 10

b = 4

_______

27 : 3 : 3 × d = 6 × 4

9 : 3 × d = 24

3 × d = 24

d = 24 : 3

d = 8

______

c : 2 : 3 = 5

c : 2 = 5 × 3

c : 2 = 15

c = 15 × 2

d = 30

________

e : 8 + 2000 = 2003

e : 8 = 2003 - 2000

e : 8 = 3

e = 3 × 8

e = 24
