Answer 2

Answer:

-0.5 and negative one-half

-1/50 and -0.02

Step-by-step explanation:

-0.5 can be rewritten as -5/10. This can be simplified to -1/2 which is the same as negative one-half.

7/10 isn't equivalent to 11/20. If you multiply 7/10 by 2/2 to get the denominator of 20, it will become 14/20 not 11/20.

-1/50 in decimal form is -0.02 so -1/50 and -0.02  are equivalent.

0.15 and 1/5 aren't equivalent because 1/5 in decimal form is is 0.2, not 0.15.
