Answer:
well the friend would be wrong because integers are represented as a non fraction so u would be right
Step-by-step explanation:
We say that there are
![x](https://tex.z-dn.net/?f=x)
girls. We equate the two expressions for the amount of sweets in the packet to get:
![6x-4=5x+3](https://tex.z-dn.net/?f=6x-4%3D5x%2B3)
Subtracting 5x from both sides and adding 4 to both sides, we see that:
![x=7](https://tex.z-dn.net/?f=x%3D7)
Since there are 7 girls, we have 7*6-4=38 sweets, using the first expression of the amount of sweets. To check our answer, we examine the second expression for the amount of sweets, for a result of 7*5+3=38 sweets. Since both of these amounts are equal, our answer seems to be correct. Thus, there are 38 sweets in a packet.
Because the fraction 2/5 can't be simplified
