Tuning Guitars How do you know if a guitar has been tuned accurately? The units on a guitar tuner are measured in cents. The units tell you how far the string tone is above or below the correct pitch. If the tone is above the target note, then the reading is positive. If the tone is below the target note, then the reading is negative. The closer the reading is to 0, the more accurate the tuning is. 2. The tuning of another guitar is less accurate than the guitars in Exercise 1. Give an example of a possible reading on the tuner for this guitar. Explain your reasoning

5/12, or 5: 12

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

lr = 24

step-by-step explanation:

note that p is the midpoint of lr. to find the measurement of lr, set the equation:

lr = lp + pr

plug in the corresponding numbers to the corresponding variables:

lr = (15) + (9)

simplify:

lr = 24

24 is your measurement of lr.
