Answer 2

0.0909, 3.25, -2.571, 1.4, -3.5

Given :- $\frac{1}{11} \frac{13}{4} \: \frac{ - 18}{7} \: 1 \frac{2}{5} \: 3 \frac{1}{2}$

To Find:- Decimal forms of the given.

SOLUTION :-

$\frac{1}{11} = 0.0909$

• It is a non-terminating repeating decimal number.

$\frac{13}{4} = 3.25$

• It is a terminating decimal number.

$- \frac{18}{7} = - 2.571$

• It is a terminating negative decimal number.

$1 \frac{2}{5} = \frac{7}{5} = 1.4$

• It is a terminating decimal number.

$- 3 \frac{1}{2} = - \frac{7}{2} = - 3.5$

• It is a terminating negative decimal number.

Note:

A terminating decimal number has an end digit. Example 1.4, 1.35, 0.15

A non-terminating decimal number has no end digit.

Example : 4.232323, 3.333, 6.2777
