Question

What is the divisor when the divident is 345 remainder 5 and the quotient 20?

Answer 1

Dividend = Divisor x Quotient + Remainder

Let divisor be x.

345 = 20x + 5

20x = 340

x = 17

Divisor = 17

Hope this helps! :)

Answer 2

Dividend= divisor × quotient + remainder

345 = divisor × 20 + 5

345-5 = divisor ×20

Divisor = 340 ÷ 20

= 17
