Fraction are confusing

a) 3 ÷ 6/7 =  3             b) 6/7 ÷ 3  =              c) 7 ÷ = 15

Step-by-step explanation:

a) 3 ÷ 6/7

To simplify this, you can change the division sign to multiplication by inverting the fraction

That is;a) 3 ÷ 6/7=  3 × 7/6 = , we can reduce the fraction by dividing the numerator and denominator by 3

That is =   = 3

Therefore,  3 ÷ 6/7 =  3

b) 6/7 ÷ 3

To simplify this, we will change the division sign to multiplication sign, and then we will invert 3 to become 1/3

× =   we can reduce the fraction to its lowest term by dividing the numerator and the denominator by  3

That is;  =  

Therefore;

6/7 ÷ 3  =  

c) 7 ÷

To simplify this, we will first change the mixed fraction to improper fraction

That is 7 =

7 ÷  =  ÷ , we will now change the division to multiplication, which make us invert to become 2

 ÷ =    × 2  The two in the numerator will cancel-out the two in the denominator, thereby leaving us with just 15

That is;

 × 2  = 15

Therefore;

7 ÷ = 15
