Answer 2

Answer:

Divisible by 7 is discussed below:

We need to double the last digit of the number and then subtract it from the remaining number. If the result is divisible by 7, then the original number will also be divisible by 7.

Consider the following numbers which are divisible by 7, using the test of divisibility by 7: 133, 273, 329, 595, 672.

(i) 133

In the number 133, double the last digit of the number 3 is 6. 13 – 6 = 7 [Now we need to subtract it from the rest of the remaining number]

Since 7 is divisible by 7.

Hence, 133 is also divisible by
