(i) $8.05$ and $7.95$ are like decimals.
(ii) $0.95,0.306,7.10$ are unlike decimals.
(iii) $3.70$ and $3.7$ are like decimals.
(iv) $13.57,1.359,135.9$ are like decimals.
(v) $5.60,3.04,0.45$ are like decimals.

Answer 1

Decimals having same number of digits on right hand side of decimals are known as like decimals and those who have different number of digits are unlike decimals.

$\left(i\right)$ Both have two digits after decimal, Hence like decimals.

$\left(ii\right)$ Two gave two digits and one has $3$ digits after decimals. Hence they are unlike decimals.

$\left(iii\right)$ One has $2$ and other has $1$ digit after decimal. So, they are unlike decimals.

$\left(iv\right)$ One has $3$ one has $2$ and has $1$ digit after decimals. So, they are unlike decimals.

$\left(v\right)$ All have $2$ digits after decimal points. So, they are like decimals,

Hence, statement $\left(i\right),\left(ii\right),\left(v\right)$ are correct
