How many 1/4 cup servings of raisins are in 7/8 cups of raisins?
Ostrovityanka [42]

Answer:

7

Step-by-step explanation:

Divide 7/8 by 1/4.  (You divide the "supply" of raisins into 1/4 cup "parts".)

\frac{7}{8} \div \frac{1}{4} = \frac{7}{8} \times \frac{4}{1} = \frac{28}{8} =\frac{7}{1} =7

Multiply 7/8 by the reciprocal of 1/4 ("flip" the 1/4).

The result is 28/8, which can be simplified ("reduced") to 7.

A company is divided into 50,000 shares. An investor purchases 1,000 shares. What percent of the company does the investor own?
AnnZ [28]

Answer:

Step-by-step explanation:

percentage is per 100.

If we have to find x as percentage of y then

formula for percentage is given by = x/y*100

_______________________________________________

Given

total no. of shares = 50,000

Share bought by investor = 1,000

Percentage of share bought by investor

= Share bought by investor/total no. of shares *100

= (1000/50000)*100 = 2%.

It means that if  there are 100 shares for company then investor owns 2 shares of the company. This makes the qualitative analysis easy.

2% percent of the company does the investor own.
