Afla numerele necunoscute ; 8:a=1 rest 3 ; si b:8=18 rest 3 ; si c:8= 1 rest 2

Answer 1

Explicație pas cu pas:

$8 \div a = 1 \: rest \: 3 = > a \: = \: (8 - 3) \div 1 = 5 \div 1 = 5$

$b \div 8 = 18 \: rest \: 3 = > b = 8 \times 18 + 3 = 147$

$c \div 8 = 1 \: rest \: 2 = > c = 8 \times 1 + 2 = 10$

Answer 2

Explicație pas cu pas:

8:a=1 rest 3

a=(8-3):1

a=5:1

a=5

verific:

8:5=1 rest 3✔

5

3

b:8=18 rest 3

b=8×18+3

b=144+3

b=147

verific:

147:8=18 rest 3✔

8

=67

64

=3

c:8=1 rest 2

c=8×1+2

c=8+2

c=10

verific:

10:8=1 rest 2✔
