Question

identify the multiple of 4from the following list of numbers 4,87,24,103,28
​

Answer 1

Answer:

$\sf \green {\therefore \: Multiples \: of \: 4 \: from \: the \: following = }$ $\sf \green {4, \: 24, \: 28}$

Step-by-step explanation:

For finding the multiple of 4, the best way is finding whether it is divisible by 4 or not.

Divisibility rule of 4:- Last two digits should be divisible by 4. Because 100 is divisible by 4 (i.e.), 25 × 4 = 100.

i) 4

$\sf \frac{ \cancel4}{ \cancel4} = 1$

$\sf \green {\therefore \: 4 \: is \: divisible \: by \: 4.}$

ii) 87

$\sf \frac{87}{4} = 21.75$

$\sf \red {\therefore \: 87 \: is \: not \: divisible \: by \: 4.}$

iii) 24

$\sf \frac{ \cancel{24}}{ \cancel4} = 6$

$\sf \green {\therefore \: 24 \: is \: divisible \: by \: 4.}$

iv) 103

$\sf \frac{103}{4} = 25.75$

$\sf \red {\therefore \: 103 \: is \: not \: divisible \: by \: 4.}$

v) 28

$\sf \frac{ \cancel{28}}{ \cancel4} = 7$

$\sf \green {\therefore \: 28 \: is \: divisible \: by \: 4.}$

In this answer, we learnt:

• Divisibility rule of 4:- Last two digits should be divisible by 4. Because 100 is divisible by 4 (i.e.), 25 × 4 = 100.
