(a) (-4/5) ÷(-3)
(b) (-8/19)+(-2/57)
(c) (3/7)×(-2/5)



Want not only the answer want step by step explanation.
Then I will mark it as brainliest answer.​

Answer 1

Answer:

-4/5/-3

=-4/5×-3

because -3was in divide then if we take -3 upside it convert ×-3 then we get answers

=12/5

Answer 2

Answer:

1. (-4/5)÷(-3) = 4/15
2. (-8/19)+(-2/57). = -26/57
3. (3/7)×(-2/5) = 6/35

Step-by-step explanation:

1. (-4/5)÷(-3) =-4/5×1/-3. (because we changed divide into multiply)

then -4 ×1 = -4 and 5×(-3) = -15. = -4/-5and cut minus and minus and get 4/15

2. (-8/19)+(-2/57) = -8/19 -2/57. (because (-)×(+) =. - .then we take L.C.M. of 19 and 57 =57 .-24-2/57=.

-26/57.

3. (3/7)×(-2/5) =it is directly multiply

then3×(-2) and (7×5)

then -6/35
