1/5 full =250g
4/5 full =550g
550g-250g=300g=3/5 without jug
1/5 without jug=300g/3=100g
250g-100g=150g

<u>The jug weighs 150g empty</u>

David and Patti each decomposed 138. David wrote 1 + 1/8 + 3/8. Patti wrote 4/8+2/8+5/8.

BaLLatris [955]

Answer:

Both are wrong.

Step-by-step explanation:

We have that:

Both decomposed the fraction $\frac{13}{8}$ into a sum of fractions. Whoever's decomposition sum has a value of $\frac{13}{8}$ is correct.

David:

$1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}$

$\frac{12}{8} \neq \frac{13}{8}$ , which means that David is wrong.

Patti

$\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}$

$\frac{11}{8} \neq \frac{13}{8}$ , which means that Patti is wrong.

So the answer is that both are wrong.
