1 answer:

The 9 is in the tenths place so it should be 9x1/10. Meaning it would be 100+3x1+9x1/10+3x1,000

Answer:

$-\frac{21}{10}$ or $-2.1$ (they're the same)

Step-by-step explanation:

Simplify: $-\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}$
Find a common denominator. The LCM of 6 and 5 is 30, so multiply the numerator and the denominator by the same thing: 6 × 5 = 30, -9 × 5 = -45, 5 × 6 = 30, 3 × 6 = 18
Write the new fractions: $-\frac{45}{30} - \frac{18}{30}$
Subtract: -45/30 - 18/30 = $-\frac{63}{30} = -\frac{21}{10}$
