For a science experiment, Mr. Barrows divides 3/4 cup of salt into small jars, each containing 1/10 cup. If he has 1/7 cup of salt left over, how many jars does he fill? Enter an expression you could use to solve the problem.

Kindly check explanation

Step-by-step explanation:

Given that :

Initial cup of salt = 3/4 cups ; divided into small jars

Fraction of salt in small jars = 1/10 cup

Fraction left over = 1/7 cup

Number of jars filled?

The fraction divided into the jars :

Initial amount - left over

3/4 - 1/7

(21 - 4) / 28

17 / 28

Fraction of salt per jar = 1/10

Number of jars filled :

Total fraction divided into jars / fraction of salt per jar :

(17 / 28) ÷ (1 /10)

(17 / 28) * (10 / 1)

170 / 28

= 6.0714

= 6 jars

the 3rd on is correct
