No bc Lisa didn’t add all of the numbers together. When finding the mean you add all numbers together then divide by how many numbers you have.

Answer: 3/4 is 0.0075.

3/25 is 0.0012

Step-by-step explanation:

When you convert 3/4 into a decimal it is 0.75% but to change that into a decimal you have to move the decimal 2 place values and then 0.75% become 0.0075. The same happens for 3/25. 3 divided by 25 is 0.12% but when you move it 2 place values to the left then it becomes 0.0012.

For number eight the answer is 7 and 1/2

For number nine it is 16/24 = 2/3 If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction

For number 10 the least common denominator of 8/15 is 120, and for 7/24 it is 168

Answer:

$\frac{d-5c}{5d^2}$

$\frac{2}{y}$

21nk

Step-by-step explanation:

$\frac{1}{5d}- \frac{c}{d^2} \\$

We need to get the denominators to be the sameso what can you do to 5d and d^2 to be the same? If you multiply 5d by d you get 5d^2 and if you multiply d^2 by 5 you get 5d^2. And whatever you have to do to the denominator you do to the numerator.

$\frac{d}{d}*\frac{1}{5d}-\frac{5}{5}*\frac{c}{d^2}\\\frac{d}{5d^2}-\frac{5c}{5d^2}\\ \frac{d-5c}{5d^2}$

Once you have the same denominator you can just add or subtract the numerators as needed. You don't need to do this for multiplication or division

Multiplying is super easy, just multiply the denominators and the numerators.

$\frac{3x}{y^2}*5y\frac{2}{15x} \\\frac{3x}{y^2}*\frac{5y*2}{15x}\\\frac{3x}{y^2}*\frac{10y}{15x}\\\frac{3x*10y}{y^2*15x}\\\frac{30xy}{15xy^2}\\\frac{2}{y}$
