Question

Afla termenul necunoscut din relatile d-4/7=3 /7 ; b-1/5=3/5;e+1/5=4/5;c-2/8=4/8 ;f+3/6=9/6 Va rog!!Dau coronița

Answer 1

d - 4 / 7 = 3 / 7

d = 3 / 7 + 4 / 7

d = 7 / 7

b - 1 / 5 = 3 / 5

b = 3 / 5 + 1 / 5

b = 4 / 5

e + 1 / 5 = 4 / 5

e = 4 / 5 - 1 / 5

e = 3 / 5

c - 2 / 8 = 4 / 8

c = 4 / 8 + 2 / 8

c = 6 / 8

f + 3 / 6 = 9 / 6

f = 9 / 6 - 3 / 6

f = 6 / 6

Answer 2

Răspuns:

Explicație pas cu pas:

d- 4/7 = 3/7

d = 3/7 + 4/7

d = 7/7

7/7 - 4/7 = 3/7

b - 1/5 = 3/5

b = 3/5 + 1/5

b = 4/5

4/5 - 1/5 = 3/5

e + 1/5 = 4/5

e = 4/5 - 1/5

e = 3/5

3/5 + 1/5 = 4/5

c - 2/8 = 4/8

c = 4/8 + 2/8

c = 6/8

6/8 - 2/8 = 4/8

f + 3/6 = 9/6

f = 9/6 - 3/6

f = 6/6

6/6 + 3/6 = 9/6
