Answer:

3 2/3 square feet.

Step-by-step explanation:

You just need to multiply 6 and 4 2/3. To do this you have to change both of them into improper fractions so 6 would be 21/3 and 4 2/3 would be 14/3. If you cross cancel the 21/3 will become 7/3 and the 14/3 will become 14/1. Now you have to multiply across and you should get 98/3. To change the improper fraction into a mixed number you have to divide 98 and 3 so you can get 3 2/3. Therefore, the answer to the area of the quilt is 3 2/3 square feet.

There are 11 trains containing giraffes and 7 trains containing rabbits.

<h3>Equation</h3>

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of train with giraffes and y represent the number of train with rabbits.

Hence:

25x = 40y

25x - 40y = 0    (1)

Also:

25x + 40y > 500   (2)

From both equations:

A possible solution is x = 11, y = 7

There are 11 trains containing giraffes and 7 trains containing rabbits.
