Answer:
1. -29/156 2. 38/45 3. 29/45 4. 113/24 or about 4.7 5. 457/1, 914/2, 1371/3
Step-by-step explanation:
3/13 - 5/12 can be simplified to 36/156 - 65/156. Subtract this and you get -29/156
4/9 + 2/5 can be simplified to 20/45 + 18/45. Add this and you get
38/45
5/8 - 2/9 can be simplified to 45/72 - 16/72. Subtract this and you get
29/45
3 1/2 + 2 5/12 can be first made irrational to 7/2 + 29/24. This can be simplified to 84/24 + 29/24
113/24 or about 4.7
Not sure about the 457, but to convert it, you multiply it by whatever denominator you have. For example
1x457 = 457/1
2x457 = 914/2
And finally 3x457 = 1371/3

Answer: Option 'B' is correct.
Our net price will be $3357.21.
Explanation:
Since we have given that
The list price of set of saws = $3800
There are 3 successive discounts :
8%,3%,1%
So, if we apply first for 8% discount our new price becomes,

Now, if we apply 3% on our deducted price , our new price becomes ,

Now, we'll apply for 1% on our new deducted price , our net price becomes,

Hence, our net price will be $3357.21.
Therefore, Option 'B' is correct.
