I thought of a number, I added 1 3 4 to it, then I multiplied the result by 2 2 11 and I got 8. What was my number?
Natalija [7]

Question:

I thought of a number, I added 1 3/4 to it, then I multiplied the result by 2 2/11 and I got 8. What was my number?

Answer:

The number is 1\frac{11}{12}

<em></em>

Step-by-step explanation:

Let the number be x.

Analyzing the steps, 1 at a time

Add 1\frac{3}{4} to x

This implies:

x + 1\frac{3}{4}

Multiply by 2\frac{2}{11} to result in 8

This implies:

(x + 1\frac{3}{4}) * 2\frac{2}{11} = 8

Now, we solve for x

Convert mixed numbers to improper fractions

(x + \frac{7}{4}) * \frac{24}{11} = 8

(\frac{4x + 7}{4}) * \frac{24}{11} = 8

Multiply through by 11

11 * (\frac{4x + 7}{4}) * \frac{24}{11} = 8 * 11

(\frac{4x + 7}{4}) * 24 = 88

Divide through by 24

(\frac{4x + 7}{4}) * 24/24 = 88/24

\frac{4x + 7}{4} = \frac{88}{24}

Multiply through by 4

4 * \frac{4x + 7}{4} = \frac{88}{24} * 4

4x + 7 = \frac{88 * 4}{24}

4x + 7 = \frac{88}{6}

4x + 7 = \frac{44}{3}

Make 4x the subject

4x = \frac{44}{3} -7

4x = \frac{44-21}{3}

4x = \frac{23}{3}

Solve for x

x = \frac{23}{3 * 4}

x = \frac{23}{12}

x = 1\frac{11}{12}

<em>Hence, the number is </em>1\frac{11}{12}<em></em>
