Answer:
FRACTION FORM P=3/4
DECIMAL FORM P=0.75
Step-by-step explanation:
1)Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
2) simplify 21/20
3) 3 21
(— • (p + 1)) - —— = 0
5 20
4) 3 • (p + 1) 21
——————————— - —— = 0
5 20
5)calculate the least common multiple
6)left denominator is 5
7) right denominator is 20
8)so lcm is 20
9)calculate multipliers for both fractions
10) rewrite both into equivalent fractions
11) then multiply the numerator of each fraction
12)Add the two equivalent fractions which now have a common denominator
13)pull out the like factors
14)get rid of the denominator
15)the 20 cancels out on the left side
16)Add 3 to both sides of the equation :
4p = 3
17)Divide both sides of the equation by 4:
p = 3/4 = 0.750
