<u>15/2</u>
Step-by-step explanation:
- 30/4=7.5
- convert the decimal to a fraction
- 7.5 would give you 15/2 in fraction form
- since you can't simplify 15/2 anymore, <u>15/2</u> would be your answer.
Hello!
You have to find 45% of 2,920
First change 45% to a decimal
To change percents to decimal, remove the % sign and add a decimal point 2 places to the left.
45% = 0.45
<em>Now multiply</em>
0.45 × 2,920 = 1,314
There are <u>1,314 </u>advertising pieces
I believe that it is a concurrent power
To figure this out, we need to use fractional proportions.
Currently, we have $120, the amount earned, and 2 days, the current rate.
Our fraction for this is: 120 / 2 = x / 6, x being the amount earned in 6 days.
Let's use a little technique to help us answer faster.
With our current money earned, 120, and our current days, 2, we can divide 120 by 2 to find out how many we earned in 1 day.
120 / 2 = 60.
We earned $60 per day.
With this formula, 60d, d being the amount of days, we can solve quicker.
We are solving for 6 days, so multiply $60 by 6 days.
60 x 6 = 360
Your proportion is :
120/2 : 360/6
I hope this helps!

if the number is –2
then
[2(-2) - 3] / (-2)^2
= (-4-3)/4
= -7/4
