Notice how 1/2 and 3/8 are positive numbers. We add two positive numbers meaning that the result should be larger. However 2/5 = 0.4 is not larger than 1/2 = 0.5

So something went wrong with the adding. It turns out that the error is when the person added the numbers in the denominators (2 and 8 to get 10). This is not allowed. The denominators must be the same and stay the same in order for the fractions to be added.

For example: 1/7 + 2/7 = (1+2)/7 = 3/7
The 7s in the denominator do not change

Therefore the answer is choice B) Not true because 2/5 < 1/2

The number of customers on the first day are (6×-3) the number of customers on the second day is (×-1) how many more customers v
EleoNora [17]

The number of customers who visited more on first day = ( 5 x - 2)

<h2>248 more people visited on the first day. </h2>

Step-by-step explanation:

The total number of customers visiting on first day  = (6 x - 3)

The total number of customers visiting on second day  = (x - 1)

The difference in the number of customers

= Number of customer visiting ( First day - Second Day)

= (6x  - 3) - (x- 1)  = 6 x - 3 - x +  1  = 5 x - 2

So, the number of customers who visited more on first day = ( 5 x - 2)

Now, when x  = 50, ( 5 x - 2) = (5 (50) - 2)  = 250 - 2  = 248

Hence, 248 more people visited on the first day.
