Black_prince [1.1K]

Answer:

  11/12

Step-by-step explanation:

(1 1/10)/(1 1/5) = 1.1/1.2 = 11/12

__

You can also work this using improper fractions:

(1 1/10)/(1 1/5) = (11/10)/(6/5) = 11/10×5/6 = (11×5)/(6×10)

The length of a rectangle is 5 more than twice the width. the perimeter is 130 inches. what is te area
Brut [27]
The length of a rectangle:
L =  2 W  + 5
The perimeter:
P = 2 L + 2 W
130 = 2 · ( 2 W + 5 ) + 2 W
130 = 4 W + 10 + 2 W
130 - 10 = 6 W
120 = 6 W
W = 120 : 6
W = 20 in
L = 2 · 20 + 5
L = 40 + 5
L = 45 in.
Finally the area:
A = L · W
A = 20 · 45
A = 900 in²
