This question is really hard

Answer:

1. \frac{1}{4}

2.\frac{5}{6}

3.\frac{3}{10}

4. 1\frac{1}{8}

5. 2\frac{6}{7}

6. 3\frac{8}{9}

<u>Step by Step Explanation</u>

I used the same method with all 6 questions, I had to tweak it slightly for the last 3 as they were mixed fractions.

For the first 3 questions, I used the number you had to make and multiplied it by the denominator. Let's use the first questions as an example.

We need to make 7 by adding something to 27/4. I multiplied 7 by 4 in order to get 28.

This means your goal is to get to 28/4.

The difference between 28/4 and 27/4 is 1/4. Meaning you only have to add 1/4 in order to make 7.

For the last 3 questions I first sorted the fractions out. Let's use the first question again on the right side as an example.

I made 5\frac{7}{8} a top heavy fraction by first multiplying 5 by 8, which makes 40. I then added 40 to 7 making 47. Now the fraction is 47/8.

Now that we have our top-heavy fraction we do the same as last time. We need to make 7. So we multiply 7 by 8 and that makes 56. The difference between 56 and 47 is 9. So we need 9/8 in order to get to 56/8. We need a mixed fraction so 9/8 becomes 1\frac{1}{8}.

I hope this helps, if this was confusing don't be afraid to ask questions.

How to do this problem 15: x +17 =32
Juliette [100K]
SO x plus 17 are equal to 32. That means you know that 17 plus some unknown number can equal 32. To find this number, simply subtract 17 on both sides. This will get you x=15. Hope it helps.

Acidity is measured on the pH scale. The acidity of a substance is given by pH=−logH, where H is the concentration of Hydrogen i
trapecia [35]

Answer:

[H^{+} ]= 10^{-pH}

Step-by-step explanation:

To solve this question it is important to remember logarithm rules. That is:

a^{y} =x\\\\logx_{a} = y

pH = -log[H^{+}]\\\\-pH = log_{10}[H^{+} ]\\\\H^{+}] = 10^{-pH}\\

Answer:

-134

We cannot make a "mixed number" because -536-4 can already be divided...
