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

Answer:

Total paint left over = $\frac{13}{12}L$

Step-by-step 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 = $(\frac{5}{4} + \frac{1}{2})L$

                          = $\frac{5 + 2}{4}L$

                          = $\frac{7}{4}L$

⇒Total mixture =  $\frac{7}{4}L$

Now,

Given that ,

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

So, total mixture left = $(\frac{7}{4} - \frac{2}{3})L$

                                = $\frac{21 - 8}{12}L$

                                = $\frac{13}{12}L$

∴ we get

Total paint left over = $\frac{13}{12}L$
