Answer down below!
Step-by-step explanation:
The simple way to do this is shown below:
Since two tires cost $74, you know that if you multiply that by two, you'll get your four.
74 x 2 = 148
<em>Four tires will cost you $148</em>
Just multiply "6/8" times 5.
(6/8)(5)
(6/8)(5/1)
*Find common denominator. Which is 8, so multiply "5/1" by 8.
(6/8)(40/8)
- Once you have the same bases, you multiply across.
240/8
-You can simplify this fraction by dividing by 8.
30.
- 30 is your answer.
