Find 6.75% of 260 plzzzzzzzzzzzzzzzzzzzzzzzzzzzz helppppppppppppppp
ICE Princess25 [194]

Answer:

17.55

Step-by-step explanation:

. We assume, that the number 260 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 260 is 100%, so we can write it down as 260=100%.

4. We know, that x is 6.75% of the output value, so we can write it down as x=6.75%.

5. Now we have two simple equations:

1) 260=100%

2) x=6.75%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

260/x=100%/6.75%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 6.75% of 260

260/x=100/6.75

(260/x)*x=(100/6.75)*x       - we multiply both sides of the equation by x

260=14.814814814815*x       - we divide both sides of the equation by (14.814814814815) to get x

260/14.814814814815=x

17.55=x

x=17.55

now we have:

6.75% of 260=17.55

Biochemistry lab is worth 25% of your total MCB 2000 course grade. Of that 25%, the weekly laboratory reports account for 45%. F
Oksi-84 [34.3K]

Answer: 1%

Step-by-step explanation: Total 2,000

BioChem Lab: 25% of total = 25% . 2000 = 500

LabRep: 45% of Lab = 45% . 500 = 225

There will be 9 LabRep: 225/9 = 25

Participation: 10% of LabRep = 10% . 25 = 2.5

Actual LabRep: 90% of LabRep = 90% . 25 = 22.5

So, each lab report is worth 22.5 of 2000 = 2.5/2000 = 0.01125 = 1.125%

Nearest whole number = 1%
