Question

What is 1 4/5 + (-3 4/10) show your work !

Answer 1

Answer:

$-\frac{8}{5} = -1\frac{3}{5}$

Step-by-step explanation:

$1 \frac{4}{5} = \frac{9}{5}$

$-3 \frac{4}{10} = -\frac{34}{10} = -\frac{17}{5}$

Multiply the whole number by the denominator and add that to the numerator. I simplified $-\frac{34}{10}$ by dividing by two getting $-\frac{17}{5}$. Then add $\frac{9}{5}$ and $-\frac{17}{5}$ together. Then put $-\frac{8}{5}$ into a mixed fraction. How many times does 5 go into 8 and what is the remainder? The answer is -1 times and the remainder is 3. The mixed fraction is $-1 \frac{3}{5}$.
