-2 and 1/3 times 1 and 1/2=
torisob [31]

Answer:

-2\frac{1}{3}\times 1\frac{1}{2}=-3.5

Step-by-step explanation:

We are asked to find the product of -2\frac{1}{3} and 1\frac{1}{2}.

Upon writing our expression as a product we will get,

-2\frac{1}{3}\times 1\frac{1}{2}

Let us convert our given mixed fractions to improper fractions.

\frac{-7}{3}\times \frac{3}{2}

Upon cancelling out 3 from our given expression we will get,

\frac{-7}{2}

Upon dividing -7 by 2 we will get,

\frac{-7}{2}=-3.5

Therefore, our expression simplifies to -3.5.
