HELLO!!❤

YOUR ANSWER↓

Step-by-step explanation:

It is terminating because↓

421/10 = 42.1

Hence,it has an end.

HOPE IT HELPS YOU ❤

Answer 2

${\sf{\lagre{\underline{\bold{\underline{Answer}}}} \ :-$

$\dfrac{421}{10}\ \sf{is\ a\ terminating\ decimal\ expansion.}$

${\sf{\lagre{\underline{\bold{\underline{Explanation}}}}\ :-$

• We know that a terminating decimal is a decimal that ends. It's a decimal with a finite number of digits.

• For example 1/4=0.25, it has only two decimal digits.

We can write 421/10 as 42.1 (Decimal Form)

The resulting decimal number ends with 1 decimal digits and therefore, it is terminating decimal.

$\sf{Hence,} \dfrac{421}{10}\ \sf{is\ a\ terminating\ decimal\ expansion.}$

Rational number has two types of decimal expansion

• Terminating decimal expansion.

• Non-terminating decimal expansion.

Irrational number has one type of rational number

• Non-terminating non-repeating decimal expansion
