0.52 - 0.4 = 0.12
52/100 - 40/100 = 12/100

Using grids divided into tenths instead of hundreds would make for much more efficient counting.
1/10 0f 1 is .10 or one tenth of a whole. Therefore, there are 10 tenths in a 1, as would be 100 hundredths in 1.
You put the whole number of dollars to the left of the decimal and the cents to the tenths and hundredths. EXAMPLE: $15.83 = 15.83
If you want to make 0.1 (one tenth) into one hundreth, you move the decimal point over one to the left like this : 0.01
5/10 Just make it hundredths by using a common denominator gotten by a form of one. 10*5/10*10 = 50/100 ( 50 hundredths ) ---------------------- ( 50/100 = 0.5 in decimal and 5/10 also = 0.5 as a decimal )
They make 0.36
0.1
Round it up or down. Examples: 0.014 (thousandths ) is 0.01 (Hundredths) and 0.0 (Tenths) 0.567 (Thousandths) is 0.57 (Hundredths) and 0.6 (Tenths) 27.499 (Thousandths) is 27.50 (Hundredths) and 27.5 (Tenths)
7.09 as 7.9 is seven and nine tenths so add a 0 to make it seven and nine hundredths.

119 must be taken away from 519 to make 400.
40 x .3Remember: 0 . (tenths) (hundredths) (thousandths)In this case (I missed it the first time) it's 30 hundredths, or 3 tenths(4 x 10) x .3Factoring out the 10 for the next step.4 x (10 x .3)Moving the 10 to the other side to make this easier to do in your head4 x 3 = 12
If you want to make 0.1 (one tenth) into one hundreth, you move the decimal point over one to the left like this : 0.01
no .05 is 5 hundredths, meaning that it takes one hundred hundredths to make a whole whereas .1 is one tenth meaning to takes only ten tenths to make a whole, same with thousandths and ten thousandths etc.
5/10 Just make it hundredths by using a common denominator gotten by a form of one. 10*5/10*10 = 50/100 ( 50 hundredths ) ---------------------- ( 50/100 = 0.5 in decimal and 5/10 also = 0.5 as a decimal )
