Explicație pas cu pas:
7/10 - a = 5/10
a = 7/10 - 5/10
a = 2/10 :2 = 1/5
b + 3/9 = 7/9
b = 7/9 - 3/9
b = 4/9
2/4 + c = 4/4
c = 4/4 - 2/4
c = 2/4 :2 = 1/2
d - 1/3 = 4/3
d = 4/3 + 1/3
d = 5/3
3/10 + 6/10 - e = 2/10
9/10 - e = 2/10
e = 9/10 - 2/10
e = 7/10
f - ( 56 /100 + 31/100 ) = 61/100
f -87/100 = 61/100
f = 61/100 + 87/100
f = 148/100 :4 = 37 /25
9/10 - g = 7/10 - 3/10
9/10 - g = 4/10
g = 9/10 - 4/10
g = 5/10 :5 = 1/5
h + 3/4 + 2/4 = 10/4 - 1/4
h + 5/4 = 9/4
h = 9/4 - 5/4
h = 4/4 : 4 = 1
