PLSS HELP ME

Answer 1

Answer:

4236

as its last digits are multiple of 4

36

Answer 2

Answer:

a) 4236

for divisibility by 4, if the last two digits of a number are divisible by 4 then the number is divisible by 4

here, 4236 has its last two digits as 36 which when divided by 4 gives 9 i.e, it is divisible by 4

but in the case of 254 54 is not divisible by 4

so 254 is not divisible by 4

similar is the case with divisibility by 8 where if the last three digits of a number are divisible by 8 then the number is divisible by 8

Step-by-step explanation:

hope it will help you

for divisibility by 2 if the last digit is divisible by 2 then the no. is divisible by 2

for 3&9 if the sum of digits of the no. is divisible by them then the no. is divisible by 3&9

for 5 the last digit of the no. should be 0 or5
