Responder:
29/35; 6/35
Explicación paso a paso:
Dado que:
Fracción con soja = 2/5
Fracción con maíz = 3/7
Fracción total de la finca sembrada:
Fracción con soja + fracción con maíz
2/5 + 3/7
L. C. M = 35
(14 + 15) / 35 = 29/35
Fracción de la finca. Izquierda :
1 - 29/35
L. C. M = 35
(35 - 29) / 35 = 6/35

Answer:
The level was 402.7ft. at the end of two weeks.
Step-by-step explanation:
First, we need to find the amount of decrease for the first week.
520 x 0.12 = 62.4
Now, we subtract the change for the first week.
520 - 62.4 = 457.6
Next, we find the change for the second week.
457.6 x 0.12 = 54.912
Then, we subtract the change for the second week.
457.6 - 54.912 = 402.688
And we are left with our final answer that is 402.688ft. or if you wish to round to the nearest tenth, then your answer would be 402.7ft.
Step-by-step explanation:
a)
well, it is kind of written already :
228 miles and 6 gallons.
so, miles/gallon = 228/6 = 38 miles/gallon.
b)
it is not mentioned, but I guess we have to assume that he got the same miles/gallon ratio on this trip as well.
so, again
38 miles/gallon
and he used 9 gallons.
so, he drove 38×9 = 342 miles
