Answer 1

Multiply 7 by each of the fractions to find the solution that is less than 7


= 7 * 4/4
= (7*4)/4
= 28/4
= 7

= 7 * 4/3
= (7*4)/3
= 28/3
= 9 1/3

= 7 * 4/5
= (7*4)/5
= 28/5
= 5 3/5

= 7 * 4/1
= (7*4)/1
= 28/1
= 28


ANSWER: The fraction that gives a solution less than 7 is 4/5. 4/5 multiplied by 7 is 5 3/5.
