-1 3/5 divided by (-2/3) write as mixed number
hichkok12 [17]

Step-by-step explanation:

- 1  \frac{3}{5}  \div  \frac{ - 2}{3}

Convert the mixed numbers above to improper fractions. Thus:

\frac{ - 8}{5}  \div   \frac{ - 2}{3}

In order to simplify the fractions above, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that -2/3 to -3/2. Hence,

\frac{ - 8}{5}  \times  \frac{ - 3}{2}

\frac{ - 8 \times  - 3}{5 \times 2}

=  \frac{24}{10}

= 2  \frac{4}{10}

= 2  \frac{2}{5}
