Step-by-step explanation:
Given : In 3/4 pound of a spice mix, there is 5/6 cup of cinnamon.
To find : How much cinnamon does the spice mix contain per pound?
Solution :
In \frac{3}{4}
4
3
pounds of a spice mix have \frac{5}{6}
6
5
cup of cinnamon.
So, In In 1 pounds of a spice mix have \frac{\frac{5}{6}}{\frac{3}{4}}
4
3
6
5
cup of cinnamon.
Now, we solve the fraction
=\frac{\frac{5}{6}}{\frac{3}{4}}=
4
3
6
5
=\frac{5\times 4}{6\times 3}=
6×3
5×4
=\frac{10}{9}=
9
10
=1\frac{1}{9}=1

Therefore, Option 3 is correct.
Cinnamon does the spice mix contain per pound is =1\frac{1}{9}=1

<span>Podemos resolver as equações da seguinte forma:
11) -2,6 x 10³ ----> iremos andar três casas para direita.
X = -2600 12) 5,824 x </span>
<span> ---> iremos andar duas casas para esquerda.
X = 0,05824 13) - 5,408 ---> iremos adicionar o </span>
<span>
x = </span>
- 5,408 x <span>
14) 0,00907 ----> iremos adicionar o </span>
x = 9,07 x Espero ter ajudado :)
N^2-5n-2 I think is the answer if not sorry.
