Answer:

Number of jars filled is 3
(8)/(9) (approximately 4).

Explanation:

Initial amount of salt = 1/2 cup.

Amount of salt left = 1/9 cup.

Amount of salt used = 1/2 - 1/9

=
(9-2)/(18)

= 7/18

The size of each jar = 1/10 cup.

Amount of salt used = size of the each jar x number of jars filled

7/18 = 1/10 x number of jars filled

number of jars filled = 7/18 ÷ 1/10

= 7/18 x 10/1

= 70/18

= 3
(8)/(9)

= 3.9

The number of jars filled is approximately 4.
