Question

35. Para pintar una casa se mezclaron 5/4 L do pintura blanca y 1/2 L de pintura azul. Al final solo se emplearon 213 L de la mezda,

¿cuántos litros de pintura sobraron?​

Answer 1

Total paint left over =
`(13)/(12)L`

Explanation:

Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint

were mixed. In the end only 2/3 L of the mixture were used.

To find - How many liters of paint were left over ?

Proof -

Given that,

5/4 L of white paint and 1/2 L of blue paint were mixed.

So, total mixture =
`((5)/(4) + (1)/(2))L`

=
`(5 + 2)/(4)L`

=
`(7)/(4)L`

⇒Total mixture =
`(7)/(4)L`

Now,

Given that ,

In the end only 2/3 L of the mixture were used.

So, total mixture left =
`((7)/(4) - (2)/(3))L`

=
`(21 - 8)/(12)L`

=
`(13)/(12)L`

∴ we get

Total paint left over =
`(13)/(12)L`
