The best way to solve this is to find a common denominator! Don't worry, it's super easy
Take 4 1/5 and change it to a single fraction by multiplying 5(4) and adding the 1, then put it over 5 again. This gives you 21/5, which is equal to 4 1/5.
Then do the same thing with 2 1/2:
2(2) +1 over 2= 5/2.
The problem is asking you to subtract. So 21/5- 5/2.
So how can you subtract that? Easy: common denominators!
The smallest number that is divisible by both 2 and 5 is 10, so you want both numbers to have 10 on the bottom.
To do this, multiply 21/5 by 2/2 (Note: 2/2 is equal to 1, so you are not changing the value of the fraction, you're only changing how it is written).
This is 42/10.
Then multiply 5/2 by 5/5 for 25/10.
NOW you can finally subtract!
42/10 - 25/10 = 17/10
17/10 is your answer!!
(Think 42-25/10 if you're confused on how to subtract Fractions)
The sequence is decreasing by 3 each time
So the formula would be y =27-3(x-1)
Plug in 43
Y =27-3(43-1)
Y = 27-3(42)
Y = 27-126
Y = -99
The 43rd term of the sequence would be -99
Hope this helps :)

Answer:
$26.88
Step-by-step explanation:
33.60x.20=6.72
33.60-6.72= 26.88
Answer:
1. 72%
2. 18
3. 25
Step-by-step explanation:
1. 18/25= .72= 72%
2. 9f always means to multiply so .3 times 60= 18
3. work backward so 5/20%= 25
