Question

Carlos mixed 2/10L of orange juice with 1/8L of pineapple juice. Determine a reasonable estimate of the total amount of juice Carlos mixed.

Answer 1

Answer:

$\frac{13}{40}\ liters$  or  $0.325\ liters$

Step-by-step explanation:

we know that

To find the total amount of juice Carlos mixed, sum the liters of orange juice plus the liters of pineapple juice

Let

x------> liters of orange juice

y-----> liters of pineapple juice

z----> total amount of juice mixed

so

$z=x+y$

we have

$x=\frac{2}{10}\ liters$

$y=\frac{1}{8}\ liters$

substitute

$z=\frac{2}{10}+\frac{1}{8}=\frac{4*2+5*1}{40}=\frac{13}{40}\ liters$

Convert to decimal form

$\frac{13}{40}\ liters=0.325\ liters$
