Fractions: three oil tankers together contain 37 5/7 litres of oil. If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

ale4655 [162]

Step-by-step explanation:

It is given that, three oil tankers together contain 37 5/7 litres of oil.

Total volume of oil is $\dfrac{264}{7}\ L$

If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

Oil in first tanker is $\dfrac{157}{14}\ L$

Oil in second tanker is $\dfrac{87}{7}\ L$

Oil in first and second tanker is :

$\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L$

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

$=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L$

Hence, this is the required solution.

Una botella tenía agua hasta de su capacidad. Luego, se agregó litro de agua y la botella quedó llena. Si x representa la capaci

Elena L [17]

Responder:

3 / 4x + 1/2 = x

Explicación paso a paso:

Dado que:

Capacidad total = x

Volumen inicial = cierta fracción * capacidad total

Volumen adicional agregado para llenar = 1/2

Por eso,

Inicial. Volumen + volumen adicional = volumen total

De las opciones:

Un volumen inicial de 3 / 4x

Volumen adicional de 1/2

Volumen total = x

Sumar todo hace que la ecuación:

3 / 4x + 1/2 = x

x - 3 / 4x = 1/2

Por lo tanto, la ecuación correcta de la opción es: 3 / 4x + 1/2 = x
