When multiplying fractions you multiply the denominators by the denominators and the numerators by the numerators
For example
4/5x 2/3
8/15
For starters, you should start by finding somewhere to go off of. For instance, I started with 5 pecks of whortleberries and 4 pecks of huckleberries. This game me $69 of whortleberries and $20 of huckleberries, $89 in total. This tells me I need to go up. By going steadily upwards, I'll eventually settle on 8 whortleberry pecks and 1 huckleberry peck. This is $104 and $5, which, when added together, equals $109.
Answer: 8 Whortleberry Pecks, 1 Huckleberry Peck

Answer:
8 sports tires and 9 all-season tires were sold
Step-by-step explanation:
If we let x and y represent the numbers of sports tires and all-season tires sold, respectively, then the problem statement tells us ...
6x +5y = 93
3/4x -2/3y = 0
These equations can be solved by your favorite method to find ...
x = 8
y = 9
8 sports and 9 all-season tires were sold.

<em>Additional comment</em>
My favorite method for solving systems of linear equations is a graphing calculator (when solutions are expected to be integers). If you want to do this "by hand", you can multiply the second equation by -8 and add the result to the first equation.
(6x +5y) -8(3/4x -2/3y) = (93) -8(0)
31/3y = 93
y = 9
3/4x = 6 ⇒ x = 8 . . . . substitute for y in the second equation
(sports, all-season) = (8, 9)
Let “what” be represented by x:
10 + x = -6.2
subtract 10 on both sides to get:
x = -16.2
your answer is -16.2! hope this helps!
