​

Answer 1

Answer:

0.3- three tenths, 0.5- five tenths, 0.9- nine tenths

Answer 2

Given,

Three fractions, $\frac{3}{10} ,\frac{5}{10}, \frac{9}{10}$

To Find,

To express the given fractions as decimals.

Solution,

A decimal is written for the fractions when the numerator is not exactly divisible by the denominator. A decimal point is used to separate the whole number part and fractional part of a number.

The digits after a decimal point indicate values less than one.

The decimal point for the first fraction, $\frac{3}{10}$, = $0.3$ (∵ $0.3$×10 =3)

The decimal point for the second fraction, $\frac{5}{10}$, = $0.5$ (∵ $0.5$×10 =5)

The decimal point for the first fraction, $\frac{9}{10}$, = $0.9$ (∵ $0.9$×10 =9)

Henceforth, the decimal points for the given fractions are 0.3, 0.5, and 0.9 respectively.
