Answer: 26 feet.
Step-by-step explanation:he
The exercise is not written clearly. Assuming that it asks to find the amount of lumber (in feet) John needs for 3 shelves, let "x" represents that amount of lumber in feet.
Based on the data provided, you know that one shelf requires feet of lumber.
You can convert the Mixed number to Decimal number applying these steps:
1. You must divide the numerator of the fraction by the denominator.
2. You must add the result obtained to the Whole number part.
Then you get:
Knowing this, you can set up the following proportion:
Finally, you must solve for "x" in order to find its value. This is:
1 1/4% = 1.25% = 0.0125
" of " means multiply
x = what number
0.0125x = 1.5
x = 1.5 / 0.0125
x = 120 <===1 1/4% of 120 = 1.5
Total = green marbles + red marbles + blue marbles
55 = 15 + 12 + blue marbles
55 = 27 + blue marbles
55 - 27 = blue marbles
28 = blue marbles
Answer: " 15 % " .

→ " 12 is <u> 15% </u> of 80 " .
_______________________________
Step-by-step explanation:
_______________________________
12 = (n/100) * 80 ;
12 = (80n) /100 ; Solve for "n:
Note: 80/100 = (80/10) / (100/10) = (8/10) = 0.8 ;
12 = (0.8)n ;
↔ (0.8n) = 12
Multiply each side of the equation by "10" ; to get rid of the "decimal" ;
10 * (0.8n) = 10 * 12 ;
to get:
_______________________________
8n = 120 ;
Divide each side of the equation by "8" ;
to isolate "n" on ONE SIDE of the equation; & to solve for "n" ;
8n/8 = 120/ 8 ;

to get:
_______________________________
n = 15 .

Answer: " 15 % " .
_______________________________
→ " 12 is <u> 15% </u> of 80 " .

Hey there! :D
Let's assume that 100,000 is 100%. Now, we have to find what 6% of 100,000 is.
We can do this step by step.
First, figure out what 1% of 100,000 is. To find 1% of a number, move the decimal place 2 places to the left.
So, when we move the decimal 2 places to the left, we have 1000.00. Basically, we have 1000.
So, 1000 is 1% of 100,000. Now, to find 6%, multiply 1000 by 6. So, 1000 multiplied by 6 is 6000. The final answer is 6000. The realtor earns 6000 dollars.
Thank you! Hope it helped!
