Answer:

5/7

Explanation:

-3/7 x -1 2/3

Convert to improper fraction:

3 x 1 = 3

3 + 2 = 5

-1 2/3 = -5/3

-3/7 x -5/3 = 15/21 = 5/7

Both fractions are negative, so the answer will be positive!

Answer:

5/7

Explanation:

- 3/7 × - 1 2/3 =

[a b/c = ac + b / c]

=

(-)(-)15/21 =

[2 negatives make a positive]

15/21 =

5/7

a/b × c/d = a × c/b × d = ac/bd

[reduce until the denominator or numerator is prime (only divisible by 1 and itself)]
