Mathematics

For every cubic yard, it equals to 27 cubic feet.

So, could have this fraction \frac{27 feet^3}{1 yards^3}
And we want to convert 3 cubic yards into cubic feet.

We can express 3 cubic yards as \frac{3 yards^3}{1}

Now multiply the \frac{3 yards^3}{1} fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.

\frac{3 yards^3}{1} * \frac{27 feet^3}{1 yards^2} =  \frac{81 feet^3}{1}

So, 3 cubic yards to equal to 81 cubic feet.

The ratio of forks to spoons in the cafeteria is 15:25. If the total
9966 [12]

Answer:

30 forks

Step-by-step explanation:

Let's start by simplifying the given ratio. Since both 15 and 25 are multiples of 5, we can divide the whole ratio by 5.

Forks: spoons

= 15: 25

= 3: 5

This means that forks take up 3 units of the total number of utensils, while the number of spoons is 5 units of the total number of utensils.

Number of forks= 3u

Number of spoons= 5u

Units shall be represented by the letter u from this point forth.

Now, we can form an equation using the total number of utensils in the cafeteria.

Assuming that the utensils in the cafeteria are only forks and spoons,

number of fork and spoons= 80

3u +5u= 80

8u= 80

Let's solve for u.

Divide by 8 on both sides:

1u= 80 ÷8

1u= 10

This means that 1 unit represents 10 utensils.

Substitute the value of u into the expression of the number of forks:

Number of forks

= 3u

= 3(10)

= 30

Thus, there are <u>30 forks</u> in the cafeteria.
