Have 2 digits divided by 7 remainder is 1 then halved the remainder is 1 one digit is 3 what number is it?
I think you're wanting a number of two digits, one of which is
3, that when divided by 7 gives a quotient and a remainder of 1 and
when that quotient is divided by 2 it gives a remainder of 1:
Answer: 36
36 ÷ 7 = 5 r 1
5 ÷ 2 = 2 r 1
If you want the number to be such that if it is divided by 7 the
remainder is 1 and if it is divided by 2 the remainder is 1,
then:
Answer: 43
43 ÷ 7 = 6 r 1
43 ÷ 2 = 21 r 1
