What is -9/10 • -2/3 ?

Answer 1

Multiplying two fractions together corresponds to multiplying together their components, so multiplying -9/10 · -2/3 looks like:


`(-9)/(10) \cdot (-2)/(3)= ((-9)(-2))/((10)(3))`

If we rearrange the fractions, we can perform some simplification:


`((-9)(-2))/((3)(10)) = (-9)/(3) \cdot (-2)/(10) =-3\cdot (-1)/(5)`

When gets us:


`((-3)(-1))/(5)= (3)/(5)`
