Answer 1

First convert the mixed numbers to fractions:\[-1\frac{3}{7}=-\frac{10}{7}\]
\[-3\frac{2}{3}=-\frac{11}{3}\]
Now multiply the fractions:
\[-\frac{10}{7}\times -\frac{11}{3}=?\]

Answer 2

i got -10001331

Answer 3

When the two negative signs are multiplied you get a positive sign for the answer. Now just multiply the numerators, 10 * 11= something, and multiply the denominators, 7 * 3 = something else.
Now divide 'something' by 'something else' to get the answer.

Answer 4

i got 5.2380952381 ?

Answer 5

You are right. However the answer choices are either mixed numbers or an integer.
If you divide 110 by 21 you need to do a manual long division calculation to get a mixed number answer (unlees your calculator handles fractions and mixed numbers). Can you try 110/21 using long division?

Answer 6

idk how ? i only got my phone but i think the answer is 5 5 over 21

Answer 7

Yes, good work! The correct choice is D:
\[5\frac{5}{21} \]
