I am very weak in this help me please. There are 1800 gym members in total.3/4 are aged 25 to59 years, 1/5 are over 60 years and remainder are under 25 years. How many members are under 25 years?

Steps to solve:
1. 3/4+1/5 Change both denominator to the same- 4*5=20 So far its: ?/20 + ?/20
2. For the first fraction (3/4) we do 3*5=15 Because when we found the denominators we multiplied each denominator by each other. For the second one we do pretty much the same. We do 1*4=4.
3. The final equation is 15/20 + 4/20. Now add both numerators, which is 19. You leave the denominator as it is. So the final fraction is 19/20.
4. Next to get a full fraction from 19/20 you need 1/20 to get 20/20=1. On the calculator you type in: 1/20*1800 OR... 1800/20 OR... (18/2)100
So the final answer is 90. 1800/20=90 = 90 members under the age of 25.
To solve this, we add , 3/4 + 1/5
To add fractions we different denominators we have to find a common multiple.. 4 * 5 = 20 and 5 * 4 = 20
We multiply everything by 5 (for 3/4), to get 15/20 We multiply everything by 4 (for 1/5), to get 4/20 = 15/20 + 4/20 (add the numerators) = 19/20
If 19/20 people are 25 to 60+, that means 1/20 of people are under 25
We apply this to 1800 gym members:
1800 / 20 <- get's us 1/20 of 1800 = 90
There are 90 members under 25

You would subtract each term of g(x) from f(x)
f(x) = 9x^3 + 2x^2 - 5x + 4 g(x) = 5x^3 - 7x + 4
9x^3 - 5x^3 = 4x^3
2x^2 - 0 = 2x^2
-5x - (-7x) = 2x
4 - 4 = 0
FINAL ANSWER: 4x^3 + 2x^2 + 2x

the answer is one hundredth because to the right of the decimal place is the tenths which would equal one tenth so the next place is the hundredths place whisc would equal one hundredth.
