Help please please $)

Answer 1

Look at the picture.

commutative property  a + b = b + a

... (-5 + 1/2 + 5) = ... (-5 + 5 + 1/2)

inverse property of addition a + (-a) = a - a = 0

... (-5 + 5 + 1/2) = ... (0 + 1/2)

identity property of addition a + 0 = 0 + a = a

... (0 + 1/2) = ... 1/2

inverse property of multiplication a/b · b/a = 1

37 · 2 · 1/2 = 37 · 2/1 · 1/2 = 37 · 1

identity property of multiplication a · 1 = 1 · a = a

37 · 1 = 37
