Multiply. 3/10 × (−4/5) enter your answer as a fraction, in simplified form, in the box.

Let's start with just regular fractions and let's ignore the negative sign for now. 3/10 x 4/5. Since 10 and 4 are multiples of 2, we can simplify it. so it will be 3/2 x 2/5 and you'll get 6/10. 2 can still get into 6 and 10, so the simplest form would be 3/5. Simply add the negative sign and your answer is -3/5

Multiply both the top and bottom by each other and then simplify the end fraction that you get.
So 3 times -4 would be -12 and 10 times 5 would be 50. You get -12/50 which would simplify to -6/25.
