For this case we have the following equation:
[tex] x = q * d + r
[/tex]
x: unknown number
q: quotient
r: rest of the division
d: divisor of the division
Substituting values in the given equation we have:
[tex] x = 7 * 80 + 4
[/tex]
Rewriting we have:
[tex] x = 560 + 4
x = 564
[/tex]
Answer:
The number is:
[tex] x = 564 [/tex]
The correct answer is:
564.
Explanation:
Let n be the number we are dividing. We are dividing this number by 80; we can write this expression as n/80.
Our answer is 7 with a remainder of 4. Since we are dividing by 80, we can write the remainder 4 as a fraction over 80; this gives us the quotient 7 4/80.
We will convert this to an improper fraction to find the value of n. Multiply the whole number by the denominator: 7(80) = 560. Now add the numerator: 560+4 = 564. n = 564.
