MR Zheng sold a total of 576 muffins and cookies the ratio of the number of muffins sold to the number of muffin sold to the number of cookies sold was 4:5> how many muffin were sold and how many more cookies that muffins were sold

576/9 = 64

So, there were

4*64 muffins
5*64 cookies

Divide 576 by 9, then multiply by 4 for muffins and 5 for cookies.

256 muffins
320 cookies

To find the number of muffins and cookies sold, we first need to calculate the ratio between the number of muffins and the number of cookies. The ratio is given as 4:5, which means the number of muffins is represented by 4x and the number of cookies by 5x, where x is a common multiplier.

Since the total number of muffins and cookies sold is 576, we can set up the following equation:

4x + 5x = 576

Combining like terms:

9x = 576

Now we will solve for x by dividing both sides of the equation by 9:

x = 576 / 9
x ≈ 64

Now, we can find the number of muffins sold:

Number of muffins = 4x = 4 * 64 = 256

And the number of cookies sold:

Number of cookies = 5x = 5 * 64 = 320

Therefore, 256 muffins were sold, and 320 - 256 = 64 more cookies than muffins were sold.
