Answer:

the answer is 4/7

Step-by-step explanation:

So now we have given the terms:

a) 7/5  b) 3/2  c)4/7  d) 4/3

Proper fractions are those fractions where numerator is less than denominator.

So we have:

a) 7/5=    Not a proper function

               Here numerator is 7 and denominator is 5.                                                      So numerator > denominator

b) 3/2=    Not a proper function

               Here numerator is 3 and denominator is 2.

                So numerator > denominator

c)4/7=      A proper function

               Here numerator is 4 and denominator is 7.

               So numerator < denominator

d) 4/3 =   Not a proper function

               Here numerator is 4 and denominator is 3.

                So numerator > denominator
