First, let's "get rid" of the fraction by multiplying both sides by 9.

So, we have: 324 = 5k
anonymous
  • anonymous
Then, we get k by itself by dividing each side by 5.
anonymous
  • anonymous
We now have 64.8 = k
anonymous
  • anonymous
64 4/5 would be your answer. :-)

c. l = 5 * 3 1/8

Would you like me to explain?

Yes please!

So, each piece is 3 1/8 inches long. There are five pieces in the board. To find the length of the board, we could either add 3 1/8 to itself 5 times, like this: 3 1/8 + 3 1/8 + 3 1/8 + 3 1/8 + 3 1/8 Or, we could just multiply 3 1/8 by five, like this: 3 1/8 * 5 Now, to put together the equation, we just need to say what 3 1/8 * 5 is. WHat is the solution to that problem going to represent. Well, it's going to represent the length of the board. So, we can say that l will represent length in the equation. So, we end up with: l = 3 1/8 * 5

What is the least common denominator for the 5/6 fractions and 3/8? A. 14 B. 48 C. 24 D. 18

I'm a bit confused about this one. It is phrased weirdly. I'm still trying to figure it out.
anonymous
  • anonymous
Oh, ok. I think the answer is 24. Here are instructions to find the LCD, as I can't think of how to explain it: To find the LCD first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the least common multiple (LCM) of the denominators which is equal to the least common denominator (LCD). You can then rewrite each term as an equivalent fraction with the LCD.

Which decimal is equivalent to 4 3/12? A.4.25 B.4.3 C.4.03 D.4.12
anonymous
  • anonymous
Let's simplify the fraction first. Both 3 and 12 are divisible by 3. 3/12 simplifies to 1/4. And, you probably know that 1/4 = 0.25. This means that your answer is 4.25

Justin has 6 bags of dog food. His dogs eat 3/4 bag each day. How long will his dog food last? A. 4 1/2 days B. 6 3/4 days C.8 days D.7 days
anonymous
  • anonymous
To do this, we just have to multiply 6 times 3/4. We can put 1 as the denominator beneath 6 to make the multiplication easier. 3/4 * 6/1 = 18/4 If we simplify 18/4, we get 4.5 (which is the same as 4 1/2) So the dog food will last 4 1/2 days. :-)

We will multiply the distance traveled by the number of hours. 3 3/4 * 3 1/2 We can make the multiplication much easier by converting both to fractions, instead of trying to multiply while they are mixed numbers. 15/4 * 7/2 = 105/8 This simplifies to 13 1/8
