To multiply \(-\frac{2}{5}\) by \(\frac{3}{10}\), you can use the rule that when multiplying a negative number by a positive number, the result is negative.
Here are the steps:
-
Multiply the numerators:
\(-2 \times 3 = -6\) -
Multiply the denominators:
\(5 \times 10 = 50\) -
Put together the result:
\(-\frac{6}{50}\) -
Simplify the fraction:
\(-\frac{6 \div 2}{50 \div 2} = -\frac{3}{25}\)
Thus, the answer in simplest form is \(-\frac{3}{25}\).
