In a candy mix there are 4 green bars for every 3 red bars. How many red bars are there if there are 200 green bars
erastovalidia [21]

Answer:

Since there are 4 green bars for every 3 red bars and we are trying to find the number of red bars if there are 200 green bars, we can create the ratio:

4 x : 3 y

Where  x  is equal to the number of green bars and  y is the number of red bars.

We know the number of green bars is equal to 200, so we can divide it by 4, giving us:

200 /4=50

Then we can solve for  y , the number of red bars.

// Multiple y  by 50

3 ⋅ 50 = 150

So for every 4 green bars, there are 3 red bars.

For every 200 green bars, there are 150 red bars

Xelga [282]

Given:

The equation is

\dfrac{3}{2}+b=\dfrac{7}{4}

To find:

The value of b.

Solution:

We have,

\dfrac{3}{2}+b=\dfrac{7}{4}

Subtracting both sides by \dfrac{3}{2}, we get

b=\dfrac{7}{4}-\dfrac{3}{2}

b=\dfrac{7-2(3)}{4}

b=\dfrac{7-6}{4}

b=\dfrac{1}{4}

Therefore, the value of b is \dfrac{1}{4}.
