No.
12.5 = 12 and 1/2
12 and 2/5 = 12.4
12/5ths = 2 and 2/5ths 2 and 2/5ths - 1 = 1 and 2/5th
12/5
2/5 = 40%
2 2/5
3 and 2/5ths
3 + 0.4 = 3.4
2/5:= 2 ÷ 5= 0.4 in decimal
equivalent decimal for 2 over 125 = 0.0162/125:= 2 ÷ 125= 0.016 in decimal
2 and 2 5ths... its really not that hard...
3/5 is not equivalent
