8)
348:is divisible by 4 because the last 2 digits (48) are a multiple of 4
348:is NOT divisible by 5 because the last digit is neither 5 nor 0
348:is divisible by 6 because it's divisible by 2 and also by 3
9)
23624 is divisible by 8 because te last 3 digits (624) are divisible y 8
(624/8 =78)
None of the others are divisible by 8
10) A number is divisible by 6 IF IT'S DIVISIBLE BY 2 AND BY 3:
213 NO
468 is divisible by 2 since the last digit is divisible by 2. It's also divisible by
3 since the sum of its digits [18] is divisible by 3, hence 468 is divisible by 6
621 it's divisible by 3 but NOT by 2, then it's not divisible by 6
Answer:
20% of 30
= 20/100 * 30
= 6
hence 6 students recieved A grade
