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, Friday, February 8, 2013 at 7:21pm
3/(5*6) = 3/30 = 1/10 = 0.1
times 4 = 0.4

math  Ms. Sue, Friday, February 8, 2013 at 7:22pm
(3/5)/ 6 = (3/5) * (1/6) = 3/30 = 1/10
(1/10) * 4 = ?

math  Shohanur, Friday, February 8, 2013 at 7:24pm
1/40?

math  Ms. Sue, Friday, February 8, 2013 at 7:25pm
No.
That answer doesn't even make sense.
Please study Damon's and my answers.

2/5

math  Damon, Friday, February 8, 2013 at 7:31pm
much better 2/5 = 4/10 = 0.4

math  Ms. Sue, Friday, February 8, 2013 at 7:31pm
Right.
4 portions weighs 2/5 of a pound.

I don't get how I did that

math  Ms. Sue, Friday, February 8, 2013 at 7:40pm
Both the numerator and the denominator of 4/10 are divisible by 2.
4/10 = 2/5

math  Shohanur, Friday, February 8, 2013 at 7:46pm
oh

math  Shohanur, Friday, February 8, 2013 at 7:50pm
1/10*4/1=4/10=2/5

math  Ms. Sue, Friday, February 8, 2013 at 7:51pm

math  Shohanur, Friday, February 8, 2013 at 8:29pm
3 not 4

math  Ms. Sue, Friday, February 8, 2013 at 8:36pm
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, Friday, February 8, 2013 at 8:45pm
(5/6) * (3/4) =
