Responder:
1/12
Explicación paso a paso:
Entonces multiplicamos 9 por 3 y obtenemos 27.
Luego multiplicamos 2 por 12 y obtenemos 24.
A continuación, le damos a ambos términos nuevos denominadores: 12 × 3 = 36.
Así que ahora nuestras fracciones se ven así:
27
36
-
24
36
Paso 2
Dado que nuestros denominadores coinciden, podemos restar los numeradores.
27 - 24 = 3
Entonces la respuesta es:
3
36
Paso 3
Por último, necesitamos simplificar la fracción, si es posible. ¿Se puede reducir a una fracción más simple?
Para averiguarlo, intentamos dividirlo por 2 ...
¡No! Así que ahora probamos con el siguiente número primo mayor, 3 ...
¿Son tanto el numerador como el denominador divisibles por 3? ¡Sí! Entonces lo reducimos:
3
36
÷ 3 =
<u>1/12 </u>
Let the two numbers are x and y
Let larger number = x
and smaller number = y
it means
x-y = 0.77
Now it says larger number is increased 5 times
So it now becomes 5x
So second equation becomes
5x -y =77
Now we have to solve these two equations
x-y = 0.77 and 5x-y = 77
multiply first equation by -1 and then add both equations
-x+y = -0.77
Now on adding we get
-x+5x +y -y = 77-0.77
4x = 76.23
Divide both sides by 4
x=19.0575
We get the larger number , now subtract 0.77 from this , we will get the smaller number
y=19.0575-0.77=18.2875
y=18.2875
Hence the larger number = 19.0575
Smaller number = 18.2875
Answer:
C. 60
Step-by-step explanation:
x + 10 = 70
Subtract 10 from both sides
x + 10 - 10 = 70 -10
Simplifying
x = 60
Answer:
One avocado costs $1 and one tomato costs $0.50
Step-by-step explanation:
Set up a system of equations where t is the number of tomatoes and a is the number of avocados:
4t + 8a = 10
6t + 14a = 17
Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2:
12t + 24a = 30
-12t - 28a = -34
Add them together and solve for a:
-4a = -4
a = 1
Plug in 1 as a into one of the equations and solve for t:
4t + 8a = 10
4t + 8(1) = 10
4t + 8 = 10
4t = 2
t = 0.5
So, one avocado costs $1 and one tomato costs $0.50
