There are many ways to do this. I do it by dividing 1 into 8 which is .125 and then just add the 3 in front of that which is 3.125
3.125
3.125
4.0
one eighth equals .125, so 3 eighths equal .375.
3
To change 3 and a half to a decimal you can either do 3.5, 3.50 or 3.500.A half as a decimal is 0.5 and 3 is already a decimal number so 3 and a half is 3.5 in decimal form.
3 38 into a decimal=3.38
0.75 Simplify 6 over 8=3 over 4.
3 minutes = 60 x 3 = 180 seconds one eighth of a minute = 60 ÷ 8 = 7.5 seconds 3 and one-eighth minutes = 187.5 seconds
Three times one eighth is three eighths.

3 X 10 -8 = 0.00000003 Just 0000, until just a decimal place past the whole counting number 3
