Question

A number n when divided by 14 gives a remainder 5. What is the remainder when the same number is divided by 7 ?​

Answer 1

Step-by-step explanation:

let the number be x

Since dividing the number give remainder 5 , x can be written in 14×y+5

• where y will be quotient of dividing X by 14
• X = 14×y+5
• X = 2×7×y+5
• Let divide both side by 7 then remainder when x is divide by 7
• X/7 = (2×7×y)/7+5/7
• x/7 = 2×y+5/7
• Since y is a whole number quotient of thus 2×y will be also be a whole number and remain 5/7
• thus remainder 5 when x is divide by 7
