10 12/100 = 10.12
3.10 or 3.1, if you want it in decimal form; otherwise, it's 3 10/100
12.14 The whole-number part, 12, is the part left of the decimal point. The position first right of the decimal point is the tenths place; the position second right of the decimal point is the hundredths place. We can't write "14" in the single-column hundredths place. And in fact, 10 hundredths (10/100) is the same as one tenth (1/10), so we can write a "1" in the first position right of the decimal point to stand for the ten-hundredths portion of fourteen hundredths (10 of the 14 hundredths). And the remaining four hundredths (4/100) are indicated by the 4 in the hundredths place.
10.19 = ten and nineteen hundredths.
