Decimal fractions
Fractions whose denominator is 10, 100, 1000 and so on are called decimal fractions. They are written without the denominator: first the whole part, then the decimal point, then the numerator of the fractional part. For example, 7 3/10 = 7.3 and 5 7/100 = 5.07. The number of zeros in the denominator must equal the number of digits after the point, so a zero is put in front of the numerator if needed: 4 7/1000 = 4.007. For a proper fraction the whole part is 0: 35/100 = 0.35. The first place after the point is tenths, the second is hundredths and the third is thousandths. In Uzbek, 8.52 is read as «8 whole 52 hundredths».
“Ruler decimals”: measure 4 objects (pencil, eraser, etc.) in cm and mm, then write each length in centimetres as a decimal (for example, 13 cm 6 mm = 13.6 cm).
