Question

Please help me with this

Answer 1

Answer:

• - 21/10 or  - 2.1

Step-by-step explanation:

• - 9/6 + (- 3/5) =
• - 3/2 + ( - 3/5) =
• - (15/10 + 6 / 10) =
• - 21/10

Answer 2

Answer:

$\displaystyle{ - \frac{9}{6} + ( - \frac{3}{5} ) }$

$\displaystyle{ - \frac{9}{6} - \frac{3}{5} }$

• Multiply the numerator and denominator to make it equivalent:

$\displaystyle{ = - \frac{9}{6} = - \frac{9 \times 5}{6 \times 5} = - \frac{45}{30} }$

$\displaystyle{ = \frac{3}{5} = \frac{3 \times 6}{5 \times 6} = \frac{18}{30} }$

So,

$\displaystyle{ = - \frac{45}{30} - \frac{18}{30} = - \frac{45 - 18}{30} = - \frac{37}{30} }$
