√27 = 3 is read: the cube root of twenty seven is three.
√ is called "the radical sign
" or "the sign of the root".

Fractions. Дроби.
Common fractions. Простые дроби.
Common (simple, vulgar) fractions nowadays more often than not are written on one line:
1/2, 5 3/5, 4/7, 1/3 in printing. But there are printed works where traditional writing is used:
5
7
,
4
8
, 3
5
8
etc.
Common fractions are read in the same way as we, Russians do, i. e.: the
numerator is read as a cardinal number and the denominator as an ordinal number.
If the numerator is greater than one the nominator takes the plural ending -s: 3/7 —
three sevenths, 5/8 — five eighths etc.
In mixed numbers the integer is read as a cardinal number and fraction must be
added with "and". E. g.: 3 2/5: three and two fifths; 10 2/7: ten and two sevenths.
The reading of small fractions is often simplified: 1/2 is read a half, one half,
1/3 — a third, 1/4 — a quarter; instead of: one the second, one the third, one the
fourth.
Decimal fractions. Десятичные дроби.
In decimal fractions the point (.) is used after the whole number in distinction
from Russian, where comma (,) is used and where this sign is not read. But in
Russian we must always say — десятых, сотых, тысячных и т. д., in English it is
suffice to write (.) and to say "point": 0.5 — nought [n]:t] or O [ou] point five or .5
— point five; 1.3 — one point three; 10.35 — ten point three five; 5.253 — five
point two five three; 0.001 — point OO one, or point nought nought one; point two
noughts one; point two Oes one.
After the point (.) all numbers are read separately.
