Answer:
41/5
Step-by-step explanation:
First we change the 8 and 1/5% to 8.2%
Write the fraction down as a number over one = 8.2/1
Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
8.2/1 = (8.2 × 10)
(1 × 10) = 82/10
Reduce the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD (82,10) = 2. So, (82÷2)/(10÷2) = 41/5 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 82/10 is also equal to 81/5 when expressed as a mixed number.
Answer: -14
Step-by-step explanation: 3-17= -14
17+(-14)=3
Answer: 5/2f+15
Step-by-step explanation:
2d−5f+5f=30+5f
Then,
2d=5f+30
Next,
2d/2 =5f+30/2
Around 1 or 2 because I calculated it
Answer:
581 m²
Step-by-step explanation:
The area of a trapezoid is determine as the average between the length of both bases T and B (46 and 37 m) multiplied by the height H. The area is:

Assuming that enough turf must be bought to cover the whole extension of the field, the amount of turf that should be purchased is 581 m².
