Răspuns:
Explicație pas cu pas:
7/10 - a = 5/10
a = 7/10 - 5/10 = 2/10 = 1/5
________
2/4 + c = 4/4
c = 4/4 - 2/4 = 2/4 = 1/2
_________
3/10 + 6/10 - e = 2/10
e = 3/10 + 6/10 - 2/10 = 7/10
__________
9/10 - g = 7/10 - 3/10
9/10 - g = 4/10
g = 9/10 - 4/10 = 5/10 = 1/2
___________
b + 3/9 = 7/9
b = 7/9 - 3/9 = 4/9
_____________
d - 1/3 = 4/3
d = 4/3 + 1/3 = 5/3
____________
f - (56/100 + 31/100) = 61/100
f - 87/100 = 61/100
f = 87/100 + 61/100
f = 148/100 = 74/50 = 37/25
_____________
h + 3/4 + 2/4 = 10/4 - 1/4
h + 5/4 = 9/4
h = 9/4 - 5/4 = 4/4 = 1
