Question

question 3 ANSWER FAST

Answer 1

Answer:

N BY 9 LEFT 7

SO,

WE KNOW THAT

DIVIDEND = DIVISOR × QUOTIENT + REMAINDER

==> N = 9×Q + 7

==> N= 9Q+7

SO, 3N-1/9

==> 3(9Q+7)-1 /9

==> 27Q+21 -1 /9

==> 27Q+20/9

==> 27Q+18+2/9

==> 9(3Q+2)+2/9

==> SO, REMAINDER 2 IS LEFT

SO , ANSWER = 2

                 OR

N/9 = 7

==> N-7 = 9

==> N = 16

SO, 3N-1

==> 3(16)-1 DIVIDE BY 9

==> 48-1/9

==> 47/9

==> 2 REMAINDER IS LEFT
