one cup of uncooed rice yields 3 cups of cooked rice how much uncooked rice is needed to yield 2 cups of cooke

Answer 1

Two thirds of a cup

Answer 2

My math teacher always said in algebra, what you do to one side, you do to the other.
u= uncooked
c= cooked

1u = 3c
To get to 1 cup of cooked rice you divide 3c by 3.. using the rule of what you do to one side you do to the other, the equation becomes:

(1u)/3 = (3c)/3
which equals:
1/3 u = 1c

Now that you know how much uncooked rice you need to get one cup, you multiply the formula by the total needed. In this case it's 2.
2 x (1/3 u) = 2 x (1c)

this equates to:
2/3u = 2c

if you have trouble multiplying fractions, write out the 2 as a fraction:
2/1 x 1/3
Multiple the numbers on top together and multiply the numbers on the bottom together:
2 x 1 = 2
1 x 3 = 3
giving you, your fraction of 2/3

Note: Typically when writing alegbraic equations you don't but a 1 next to a letter. You just use the letter itself, the 1 is implied. The Math and work thus becomes:
u = 3c
1/3u = c
2 x 1/3u = 2 x c
2/3u = 2c

Answer 3

1 cup uncooked = 3 cups cooked
therefore 1/3 cup uncooked = 1 cup cooked. (divide make sides by three.
2/3 cup uncooked = 2 cups cooked

The real formula is
1 cup uncooked over 3 cups cooked = x cups uncooked over 2 cups cooked, or 1/3 = x/2. Mujltiply by 6
2 = 3x x = 2/3

Answer 4

When I cook rice I use the 2 to 1 ratio....

3 cups cooked rice
3 cups water with 1.5 cups rice

2 cups cooked rice
2 cups water with 1 cup rice

1 cup cooked rice
1 cup water with 1/2 cup rice

Answer 5

First figure out the relationship of the three and the two. Ok, two is 2/3 of three. So to get 2/3 of the result, start with 2/3 of the original substance. If one gives three, then 2/3 of one would give two.

Answer 6

Set the two ratios and cross multiply.
1/3=x/2
2=3x
2/3=x

Answer 7

set it up like this 1/3=X/2 and solve for x, x =2/3

Answer 8

two thirds of a cup
