    We write the fractions divided into tenths, hundredths and thousandths. Decimal fraction is greater the greater the number nearest decimal place.

    0,33 mm = 0,3 + 0,3mm

    0,265mm = 0,2mm + 0,06mm + 0,005mm

    0,25 mm = 0,2mm + 0,05mm

    0,3 mm = 0,3

    The largest number will be the highest digit decimal fraction

    We have two numbers with the same value on the decimal place

    0,33mm, 0,3mm

    0,33mm > 0,3mm

    (0,3 + 0,03) mm > 0,3mm

    the first two numbers : 0,33mm, 0,3mm

    The other two numbers are number two on the tenth place. So we check, which has a larger number of hundreds

    0,275mm > 0,25

    (0,2 + 0,075) mm > (0,2 + 0,05) mm

    0,075mm > 0,05mm

    Answer : 0,33mm, 0,3mm, 0,275mm, 0,25mm
