Answer:

The answer is 9/20

Step-by-step explanation:

So first you gotta convert any mixed numbers into improper fractions

You muipltiy the denominator by the whole number then add that to your numerator, the denomniator stays the same.

so if you follow that it would look like this now

-1/5 (-9/4)

Since we’re multiplying by 2 negatives with each other, its gonna be positive. Multiply it normally from left to right for both the numerator and the denominator

9/20

Answer:

[tex]\frac{9}{20}[/tex]

Step-by-step explanation:

[tex]\frac{-1}{5} (-2\frac{1}{4})[/tex]

1) Change the mixed number into an improper fraction

Multiply the whole number by the denominator and add the product to the numerator

⇒ 2 × 4 = 8

⇒ 8 + 1 = 9

[tex]\frac{-1}{5} (\frac{-9}{4})[/tex]

2) Multiply the numerators and the denominators

[tex]-1*-9 =9\\5*4=20[/tex]

[tex]\frac{9}{20}[/tex]

I hope this helps!
