Multiplying decimals and/or fractions, including negative ones - 7th grade math
Examples of how to multiply decimals and/or fractions (RATIONAL NUMBERS), including negative decimals and fractions - a lesson for 7th grade math.
We also look at a multiplication 0.15 x (-2/5) which includes both a decimal and a fraction. I solve it in two different ways: using fraction multiplication, and then using decimal multiplication. The answers look different, but are equal.
Lastly, I invite the viewers to come up with situations where particular MULTIPLICATIONS would be done in real life. :)
