12/x = 52/48
12 * 48 = 52x
x = 11.07 This is one way to do it.
Let the time = x
Let the part of the lawn = y
The general equation
y = k*x
52/100 = k * 12
k = 0.043333
y = 0.043333*x
y = 0.043333* 11.08
y = 0.48 which is what it should be.
Yet another way is to let y = kx
52 = k*12
k = 52/12
k = 4.33333333
y = 4.333333 * x
y = 4.333333 * 48
48 = 4.333333 * x
x = 11.07 which is just what you should expect.
Answer:
1.4 times as long
Step-by-step explanation:
3 1/2 (convert to mixed number) --> 7/2
2 1/2 (convert to mixed number) --> 5/2
(7/2) / (5/2) --> 7/5 --> 1.4
Answer:
663.4
Step-by-step explanation:
1.55 x 10 = 15.5
4.28 x 10 = 42.8
42.8 x 15.5 = 663.4
