Tom [10]3 years ago

Answer:

1\frac{1}{2}

Step-by-step explanation:

Let's convert the mixed fraction to an improper fraction.

2\frac{1}{4} =\frac{9}{4}

Now, we divide \frac{9}{4} by \frac{2}{3}

\frac{9}{4}÷\frac{2}{3}

Cross multiply:

\frac{9}{4} *\frac{2}{3} \\\frac{18}{12} \\\frac{3}{2}

Convert improper fraction to mixed fraction:

\frac{3}{2}  = 1\frac{1}{2}

On a certain hot​ summer's day, 391 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for
Tomtit [17]

127 children and 264 adults swam at the public pool that day

Step-by-step explanation:

On a certain hot​ summer's day

  • 391 people used the public swimming pool
  • The daily prices are $1.25 for children and $2.25 for adults
  • The receipts for admission totaled $752.75

We need to find how many children and how many adults swam at the public pool that​ day

Assume that the number of children is x and the number of adult is y in that day

∵ x children swam that day

∵ y adults swam that day

∵ 391 people used the swimming pool that day

- Add x and y, then equate the sum by 391

∴ x + y = 391 ⇒ (1)

∵ The daily price for children is $1.25 per child

∵ The daily price for an adult is $2.25

∵ The receipts for admission totaled $752.75

- Multiply x by 1.25 and y by 2.25, then add the products and

  equate the sum by 752.75

∴ 1.25x + 2.25y = 752.75

- Divide each term by 1.25 to simplify the equation

∴ x + 1.8y = 602.2 ⇒ (2)

Now we have a system of equations to solve it

Subtract equation (1) from equation (2) to eliminate x

∵ (x - x) + (1.8y - y) = 602.2 - 391

∴ 0.8y = 211.2

- Divide both sides by 0.8

∴ y = 264

- Substitute the value of y in equation (1) to find x

∵ x + 264 = 391

- Subtract 264 from both sides

∴ x = 127

127 children and 264 adults swam at the public pool that day

10. The fraction 325/790 converted to a decimal and rounded to the nearest hundredths place is _____
Romashka [77]

Answer: 325/790 rounded to the nearest hundredths place is <em>0.41</em>

Step-by-step explanation:

if you divide 325/790 you get 0.411 and some other numbers. We only need to focus on these 3 numbers. 4 is the tenths place value and the first 1 is in the hundredths place value. Sense the second 1 (which is in the thousandths place value) is less than 5, we don't round the 1 in the hundredths place value up. Meaning your answer is 0.411.

Hopefully this makes sense.
