 <span>(a) you can show the concentration by: 

amount of salt / amount of water 


amount of salt 

= 30g / L 

= [ 30 * 25g ] / [ 25L ] , 25L = 1 min 

= [ 30 * 25g ] / min 


amount of water 

= 5000 + 25t 


[ 30 * 25t ] / [ 5000 + 25t ] 

= [ 30 * 25t ] / 25*[ 200 + t ] 

= 30t / [ 200 + t ] yeah 


(b) 


lim t->∞ [ 30t / ( 200 + t ) ] 

= lim t->∞ [ ( (1 / t) * 30t ) / ( (1 / t) * ( 200 + t ) ) ] 

= lim t->∞ [ 30 / ( (200 / t) + 1 ) ] 

= 30 / ( (200 / ∞) + 1 ) 

= 30 / 1 

= 30

Follow rules of exponents

When multiply an exponent with same base just add the exponents

EX: 2^2 * 2^2= 2^4

When dividing with the same base, subtract

Explain , equivalent fractions, Least common denominator
Volgvan

Equivalent fractions are those fractions that when simplified, are the same.  They reduce to the same fraction in their simplest form.

For example,  12/15 and 24 /30  are equivalent fractions.  They both reduce to 3/5 in their simplest form.


Least common denominator: it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.  

For example, if you have 3/5 + 1/4 and want to add them, you need to get a common denominator

3/5 = 6/10 = 9/15=12/20

1/4 =2/8=3/12 =4/16=5/20

We can use equivalent fractions to help us find the common denominator of 20

replace 3/5 with 12/20 and 1/4 with 5/20  

3/5 + 1/4 = 12/20 + 5/20 = 17/20
