Question

1whole¼ of a number is less than ¾ by 5. Find the number.​

Answer 1

Answer:

In the field of Rational numbers, Q , the answer is x=12 because:

12x=34x−3⇒2x=3x−12⇒x=12

But our answer could be from some other field of numbers. For example in the finite field F7 we have:

12x=34x−3⇒2x=3x−5⇒x=5

In F7 you might also note that:

12=4

34=6
