ikadub [295]

Answer:

? = 4.29

Step-by-step explanation:

Remark

Let  x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.

Equation

14/(14+ 4) = 15/(x + 15)                   Combine like terms on the left

14/18 = 15/(x + 15)                          Cross multiply

14*(x + 15) = 18 * 15                        Simplify the right

14(x + 15) = 270                             Divide by 14

x + 15 = 270 / 14

x + 15 = 19.29                               Subtract 15 from both sides

x = 19.29 - 15

x = 4.29

How can I divide thirty-three into two groups so the ratio is four to seven?
lana [24]
Look at it this way:

-- Since the two groups have the ratio of 4 to 7, then the first group has 4 parts
and the other group has 7 parts.

-- If the first group has 4 parts and the other group has 7 parts, then they have
11 parts all together.

-- Those 11 parts are all parts of 33.  There must be  ( 33 / 11 ) = 3 items in each part.

Now you can go back to the groups . . .

-- The first group has 4 parts. 
With 3 items in each part, that's (4 x 3) = 12 items.

-- The other group has 7 parts.
With 3 items in each part, that's (7 x 3) = 21 items.
