If we are to study closely the given scenario, what we are to calculate or compute for this item, is basically the least common multiple of the given numbers. To find the unknown, we are to factor out the given numbers.
Seven (7) is a prime number while 9 can be factored out into 3x3. The answer to this question is therefore, 9. Miranda has been to the store for at least 9 times.
Miranda and Savannah visit the new store and spend $7 and $9 each time respectively. Least possible number of times that Miranda has been to store is 9 times.
Least common factor is the common number, which is divisible by all the term has in a group of terms.
Each time Miranda goes to the store she plans to spend $7 and each time Savannah goes to the store she plans to spend $9.
Suppose the Miranda has been to the store at x times and Savannah has been to the store at y times.
As Miranda and Savannah have spent the exact same total amount of money at the store. Thus,
[tex]7x=9y[/tex]
As the multiple of 9 and 7 is 63. Thus the minimum amount they spent is $63.
Now as each time Miranda goes to the store she plans to spend $7. Thus to spend the minimum amount of $63, the number of times Miranda has to visit the store is,
[tex]n=\dfrac{63}{7}\\n=9[/tex]
Hence, the least possible number of times that Miranda has been to the store is 9 times.
