Answer 2

Answer:

yes number 555555 is divisible by both 7 and 5

Step-by-step explanation:

a number is divisible by 5 when the unit digit of the number is 5 or 0

since in the given unit digit is 5 so the number is completely divisible by 5

a number when we take the last digit of the number we're testing and double it. Then, subtract this number from the rest of the remaining digits. If this new number is either 0 or if it's a number that's divisible by 7, then then original number is divisible by seven.

we have 5 as our unit digit so according to the statement when we double it we get 10 and when we subtract it from the rest number ie 55555 we get 55545 and continue the process we get that the number is the multiple of 7 hence it is also divisible by 7.

hope this helps you dear.
