Answer 1

Step-by-step explanation:

Given chapter 2 Try these:

So find  

1. 7 ÷ 2/5  

So to divide a whole number by a fraction we need to multiply the whole number by the reciprocal of that fraction. So we get

So  

1. 7 x 5/2 = 35/2

So

2.  6 ÷ 4/7

So 6 x 7/4 = 42/4  

               = 21/2

3. 2 ÷ 8/9

So 2 x 9/8

   = 18/8

  = 9/4

Try these:

1. 3/5 ÷ 1/2  

So 3/5 x 2/1

= 6/5

2. 1/2 ÷ 3/5

So 1/2 x 5/3

 = 5/6

3. 2 1/2 ÷ 3/5

5/2 ÷ 3/5

5/2 x 5/3

 = 25/6

4. 5 1/6 ÷ 9/2

31/6 ÷ 9/2

31/6 x 2/9

 = 62 / 54

= 31/27
