Answer:
Melinda's statement is true.
Step-by-step explanation:
Division implies determination of the number of times that a given number would divide another given number. Example, dividing 100 by 20 means that how many 20s can we get from 100.
Melinda dividing 500 by 50 is trying to determine how many 50s can be found in 500. So that this gives 10.
i.e
= 10
Therefore, 50 would go in 500 in 10 times. Melinda's statement is true.
