Hello There!
145 is 23.39% of 620
<u><em>HOW TO SOLVE</em></u>
<u><em></em></u>
<u><em>Equation: Y = P% * X</em></u>
<u><em>We need to solve our equation for "P"</em></u>
<u><em>P% = Y/X</em></u>
<u><em>P% = 145/620</em></u>
<u><em>p = 0.2339</em></u>
<u><em></em></u>
<u><em></em></u>
<u><em>Convert decimal to percent:</em></u>
<u><em>Percent = 0.2339 * 100 = 23.39%</em></u>
Answer:
8
Step-by-step explanation:
Add all the numbers and then divide them by how many numbers there are.
(14 + 2 + 12 + 11 + 2 + 14 + 3 + 2 + 12) = 72
72/9 = 8
Keep Change Flip is the way to think about dividing fractions.
First- 4/6 divided by 4/12
Next- Change the division sign to multiplecation 4/6 time 4/12
Then- Flip the second number 4/6 times 12/4
Now multiply
48/24 this simplifies down to 2
