Question

URGENT: HELP NEEDED NOW PLEASE :(

Answer 1

1) -(5.8x14) = -406/5 = -81.2
2) (-1/3)(-1) = 1/3 = 0.3333333....
3) -2 + 1/4 / 1 + 1/2
-7/4 / 3/2
-1.75 / 1.5 = -7/6 = -1.166....7

What do you mean by “and”?????
Is it divided or add??
I’m only sure about the first one but tell me what and mean
