Answer: The price of a book increased from $20 to $25. What is the markup rate?
Perimeter is 18 1/6 feet.
Perimeter is solved by adding the length and width of the rectangle and multiplying the sum by 2.
P = 2(l + w)
length = 5 1/3 ⇒ (5*3)+1/3 = 16/3
width = 3 3/4 ⇒ (3*4)+3/4 = 15/4
In adding fractions, make sure that the denominators are the same. Both 3 and 4 are factors of 12. So, we need to multiply each fraction to get 12.
16/3 * 4/4 = 64/12
15/4 * 3/3 = 45/12
Length + Width = 64/12 + 45/12 = (64+45)/12 = 109/12
P = 2 * 109/12
P = 218/12
P = 18 2/12 ⇒ 18 1/6 feet
-4.9=-5.7+0.8
-4.9=-4.9
Answer is C
Percent means parts out of 100
so
1/5=0.20
chris+em+jam=100%=1
0.20+0.27+jam=1
0.47+jam=1
minus 0.47 both sides
jam=0.53
jam=53/100
jam=53%
jamie ate 53%
