Answer:
For example, [latex]\text{60%}=\frac{60}{100}[/latex] and we can simplify [latex]\frac{60}{100}=\frac{3}{5}[/latex]. Since the equation [latex]\frac{60}{100}=\frac{3}{5}[/latex] shows a percent equal to an equivalent ratio, we call it a percent proportion.

78
The sum is 78
Answer:
<u>The number is 170</u>
Step-by-step explanation:
Let's solve for x, this way:
x = A number that decreased by 20% of itself, the result is 136
20% = 0.2
x - 0.2x = 136 (Like terms)
0.8x = 136
x = 136/0.8 (Dividing by 0.8 at both sides)
x = 170
Let's prove that x = 170 is correct
170 - 0.2 (170) = 136
170 - 34 = 136
136 = 136
We proved that x = 170 is correct
