<h2> <u><em>
answer: </em></u>21 is 70% of 30
</h2>
<h2><u><em>
Working out percentages
</em></u></h2><h2><u><em>
We have, 70% × x = 21
or, 70100 × x = 21
</em></u></h2><h2><u><em>
Multiplying both sides by 100 and dividing both sides by 70,
</em></u></h2><h2><u><em>
we have x = 21 × 100
70
x = 30
</em></u></h2><h2><u><em>
If you are using a calculator, simply enter 21×100÷70, which will give you the answer.</em></u></h2>
1. We need to get rid of all the denominator in this equation.
- This can be done by multiplying left and right sides by the LCD.

12/x = 8 is now 12 = x * 8
1a. 8 * x = 8x
Now, your answer is 3/2, but It's improper. Let's convert it into a mixed number.

3 - 2 = 1
3/2 = 1 1/2
Therefore, your answer is 1 1/2. Also, the answer is 1.5.
I’m pretty sure this is your answer l
