Answer:

The fractional change is \frac{1}{3} % .

Step-by-step explanation:

Given as :

The original fraction = \dfrac{x}{y}

Where numerator = x

Denominator = y

According to question

The numerator decreased by 50%

Let The new numerator = x' = x - 50% of x

I,e x' = x ( 1 - \frac{50}{100})

Or, x' = x (\frac{100-50}{100})

Or, x' = \frac{50}{100} x

or, x' = \dfrac{x}{2}              .........A

Again

The new denominator = y' = y - 25% of y

i.e y' = y (1 - \frac{25}{100})

Or, y' = y (\frac{100-25}{100})

Or, y' = y (\frac{75}{100})

Or, y' = \frac{3 y}{4}              ............B

So, The new fraction = \frac{x'}{y'} = \frac{\frac{x}{2}}{\frac{3 y}{4}}

Or, \frac{x'}{y'} = \frac{2 x}{3 y}

So, The fractional change = \frac{1-\frac{2}{3} }{1} × 100

Or, The fractional change = \frac{1}{3}× 100

Hence, The fractional change is \frac{1}{3} % . Answer

The ratio of cows to goats in a farm is 3:2 if there are 210 more cows than goats how many animals are there in the farm​
hoa [83]
Answer: 350 animals altogether.

Explanation: We need to find the number of goats and add that to the 210 cows.

Since we have a ratio, we can use the equation 3/2=210/x.

Cross multiplying gives us 3x=420, where x is 140 goats.

Finally, 140+210=350.

A crew ship has 148 rooms with fifty on each of the two upper decks and the rest on the two lower decks.An upper deck room cost
AURORKA [14]
I'm not sure what your four step plan is, but here is how I would solve it:

50 rooms on each upper deck x 2 decks = 100 rooms

100 rooms x 1000 per room = 100,000

That leaves 48 rooms on the 2 lower decks, so 48/2=24 rooms per lower deck

48 rooms x 900 per room = 43,200

100,000 + 43,200 = $143,200 (maximum room sales amount)

Hope this helps!! :)
