Jess observed that 60% of the people at a mall on a particular day shopped for clothes. If 2500 people at the mall did not shop for clothes that day, the number of people who shopped for clothes that day was ______.

Answers

(3,750 people

60%=did shop

40%=did not shop =2,500

2,500/40 = x/100

40x = 2,500x100

40x=250,000

x = 250,000/40

x=6,250

6,250 =all people at the mall

6,250 - 2,500 =3,750 (60%)

(2,500 x60)/40 = 3,750

Answer:

3750

Step-by-step explanation:

2500 is 40% of 6250. 6250 - 2500 = 3750 or 60% of the people.

7 times as much as sum of 1/3 and 4/5

Answers

So the formula is
7*(1/3+1/5) = x

First find the common denominator of the fractions. In this case the common denominator of 3 and 5 is 15 so we must convert them to 15ths. To do that we divide 15 by the denominator and take that answer and multiply the numerator by it.

So for 1/3 we take 15/3(denominator) = 5 and multiply the numerator (1) by it

5 * 1 = 5 so 1/3 converts to 5/15

Do the same for 1/5 we take 15/5 = 3 and multiply the numerator (4) by it

3*4 = 12 so 4/5 converts to 12/15

Now we add 5/15 and 12/15 = 17/15 so we have our formula now to

7*17/15

We make seven a fraction 7/1 and multiply across 7*17 = 119 and 15 * 1 = 15

We have 119/15 which when we divide and get 7 14/15 as your answer

find a common denominator aka 15
so 5/15 and 12/15
= 17/15 times 7/1
119/15
