There is no ones place after the decimal so 3 is in the tenth place, so 2.4
Whenever a problem says "one number" and "another number" we can substitute x and y. for this we have x=2y+1 and xy=1. since we know the value of x (2y+1) we can substitute it for the other equation to get (2y+1)y=10. simplify to get 2y^2+y=10. from here you can do a few methods to solve this, but the simplest in my opinion is by factoring.
In order to factor it must be equal to 0, so we have 2y^2+y-10=0. We factor this and get y=5 (we also get y=-4 but it is an extraneous root). now we can plug that into either equation and find that x=2.
this means our two numbers are 5 and 2
Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.
In fact, if the daughter weights 
pound, the mother weights 
pounds, and the total weight is 
.
We know that this total is 185 pounds, so we have
So, the daughter weights 37 pounds.
Answer:
A batting average is simply the ratio of hits/at-bats. So, if Karen were up to bat 1,000 times and she got a hit 444 times, that makes her batting average 444/1,000 = .444.
The good news is you can multiply this ratio by number of at bats to get the number of hits.
So, 45 hits x .444 = your answer.
Hope that helps.
