You would just take the numbers and put them in a fraction format (10/40) then simplify (1/4) so the fraction of the total number of boats to the number of destroyers would be 1/4 :)

How many grams of solute are needed to prepare 2oz of 8% iodine solutions​
dimaraw [331]

Answer:

  4.732 grams

Step-by-step explanation:

2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.

For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.

  About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.

_____

We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.

Simone has 5 in her flower shop.Each employee works 6 4/15 hours a day how many hours in total do the 5 empoyees work per day?
kodGreya [7K]
To figure out the total amount of hours an employee works, we have to multiply the total amount of employees by the amount of hours each employee would work. 

To simplify the mixed fraction of hours they work, convert the mixed fraction into an improper fraction:

6 \frac{4}{15}

Multiply the whole number by the denominator:

6 \times 15 = 90

Add this number to the numerator to convert the mixed fraction into an improper fraction:

90 + 4 = 94

6 \frac{4}{15} = \frac{94}{15}

Now we can multiply the two numbers together (note that a whole number can be treated as the number above the denominator 1):

5 employees working 94/15 hours a day:

\frac{5}{1} \times \frac{94}{15} = \frac{470}{15}

To simplify this fraction, divide the numerator by the denominator:

470 \div 15 = 31 R 5

The whole number stays as a number, and the remainder is the new numerator:

31 \frac{5}{15}

The fraction can be further simplified by dividing both the numerator and denominator by the greatest common factor:

Factors of 5: {1,5}
Factors of 15: {1,3,5,15}

\frac{5}{15} \div \frac{5}{5} = \frac{1}{3}

31 \frac{5}{15} = 31 \frac{1}{3}

The 5 employees will work a total of 31 and 1/3 hours a day.

Jemima bought 150 oranges at ¢12 and sold them at 6 for 30gp find the profit or loss​
stepan [7]

Answer:

<h2>The loss is ¢ 4.50</h2>

Step-by-step explanation:

To calculate either the profit or loss we must first find the cost price and the selling price

<u>For the cost price</u>

She bought 150 oranges at ¢12

Cost price = ¢ 12.00

<u>For the selling price</u>

She sold 6 at 30 Gp that's ¢ 0.30

If she sold 6 at ¢ 0.30

Then 150 will be 150× 0.3/ 6

Selling price = ¢ 7.50

Since the cost price is higher than the selling price she made a loss

Loss = Cost price - Selling price

Loss = ¢ 12 - ¢ 7.50

<h3>Loss = ¢ 4.50</h3>

Hope this helps you
