Answer what property 1) 17+0=17 2)-16*1=-16 3)10*1/10=1 explain too

17 + 0 = 17
additive identity propertywhich basically states if u add a number to 0, it results in the original number

-16 * -1 = -16
multiplicative identity property...which basically states if u multiply a number by 1, it results in the original number

10 * 1/10 = 1
inverse property of multiplication...which states that any number multiplied by its reciprocal will equal 1. The reciprocal of a number can be found by just flipping the number.
examples :
10 (or 10/1)...its reciprocal is 1/10
4/5...its reciprocal is 5/4
-2 (or -2/1)...its reciprocal is -1/2
