2/35
28/70= .4 or (2/5)
56/70 = 8/10 = 4/5
69/70 can not be reduced any further
18/70 can be reduced to 9/35.
70 - 30% = 49
No.
70/100 = 7/10
70/30 = 7/3
7/10 + 4/7 = (7x7) / (10x7) + (4x10) / (7x10) = (49+40) / 70 = 89/70 = 1 + 19/70
It is: 70/100 or 7/10 in its reduced terms
70% is 70 parts of 100 so it would be 70/100. So reduced it is 7/10
70/100 reduced down it would be 7/10
