Question

what should be subtracted from 937842 to make it completely divisible by 8
​

Answer 1

Explanation:

937842-x

let x is subtracted

now 937842/8=remaindr is 4 so x =4

Answer 2

Answer:

2 must be subtracted to make 937842 divisible by 8

Explanation:

We know that,

Dividend = (Quotient × Divisor) + Remainder

Let check this,

16 ÷ 5

Q = 3 , R = 1

so,

16 = 3 × 5 + 1

Now,

If 937842 should be divisible by 8, then its remainder must be 0,

But here,

937842 = (117230 × 8) + 2

Now, to make remainder 0 we must subtract 2, so that, it becomes divisible by 8, and we know that, in an equation if an operation is done, then the same must be done on the other side as well.

So,

937842 - 2 = (117230 × 8) + 2 - 2

∴ 937840 = 117230 × 8

Now, 937840 is divisible by 8 because, it is a multiple of 8.

Thus, 2 must be subtracted to make 937842 divisible by 8.
