Question

what is the product of -3 1/4 × -1 1/2​

Answer 1

For this case we must find the product of the following expression:

$-3 \frac {1} {4} * - 1 \frac {1} {2} =$

So, we have:

$(\frac {4 * (3) +1} {4}) * (\frac {2 * (1) +1} {2}) =\\\frac {12 + 1} {4} * \frac {2 + 1} {2} =\\(- \frac {13} {4}) * (- \frac {3} {2}) =$

By law of signs of multiplication is fulfilled:

$- * - = +\\\frac {13 * 3} {4 * 2} =\\\frac {39} {8}$

ANswer:

$\frac {39} {8}$

Answer 2

Answer:

$4\frac{7}{8}$
