Reduce to simplest form
3/2 + ( -6/5 ) = ?

Step-by-step explanation: 3/2=1.5   (-6/5)=(-1.2)    1.5+(-1.2)=0.3

Answer=0.3

b.an increase in a causes b to decrease

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
