calvin buys 3/5 pound of ground beef. he divides the beef into 6 equal portions.
a)find the weight of 1 portion of beef.
b)fin the weight of 4 portions of beef.

math 
Damon,
3/(5*6) = 3/30 = 1/10 = 0.1
times 4 = 0.4 
math 
Ms. Sue,
(3/5)/ 6 = (3/5) * (1/6) = 3/30 = 1/10
(1/10) * 4 = ? 
math 
Shohanur,
1/40?

math 
Ms. Sue,
No.
That answer doesn't even make sense.
Please study Damon's and my answers. 
math 
Shohanur,
2/5

math 
Damon,
much better 2/5 = 4/10 = 0.4

math 
Ms. Sue,
Right.
4 portions weighs 2/5 of a pound. 
math 
Shohanur,
I don't get how I did that

math 
Ms. Sue,
Both the numerator and the denominator of 4/10 are divisible by 2.
4/10 = 2/5 
math 
Shohanur,
oh

math 
Shohanur,
1/10*4/1=4/10=2/5

math 
Ms. Sue,
Yay! You've got it!

Shohanur,
devon buys a plot of land with the area of 5/6 square kilometer. he divides the land equally into 4 smaller plots of land. what is the total area of 3 of the smaller plots of land?

math 
Ms. Sue,
(5/6) / 4
(5/6) * 1/4 = ______ total area of each of the plots 
math 
Shohanur,
3 not 4

math 
Ms. Sue,
This is your first step:
he divides the land equally into 4 smaller plots of land.
Then take 3/4 of that number to answer the question. 
math  an easier way? 
Ms. Sue,
(5/6) * (3/4) =

math 
Cb hfs,
