Can someone break down the basics/steps of subtracting mixed number fractions?

Mixed numbers

Step-by-step explanation:

So you have to make the mixed number then change the denominator to be the same so

for example:

25/15 - 4/3

4/3 times 5

so 4/3 is equal to  20/15

so 25/15 - 20/15 = 5/15

simplify to 1/3

they will manufacture 8496 cars

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
