126=1×62=3

2 sixths make a third

1316=2

Explanation:

For the first one and the third one, use the same concept of being able to flip the denominator if it was a fraction and change the question to multiplication.

For the second one, what you do is multiply 16 by 2 to get 13

16×2=26=13

1÷26=3

It takes two sixths to make 13

13÷16=2

Explanation:

Using the shortcut method

Part 1: 1÷26

So that you fully understand what is going on write 1 as 11

11÷26 turn the 26 upside down and multiply

11×62 = 1×61×2=62

62=6÷22÷2=31=3
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Part 2: how many sixths make 13

Let the unknown number be x

x6=13

Multiply by 1 and you do not change the value. However, 1 comes in many forms so you can change the way a value looks without changing 'what it is worth'.

x6=13×1

x6=13×22

x6=1×23×2=26

So it takes two sixths to make 13
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Part 3:What is 13÷16

Using the shortcut method of turning upside down and multiplying

13÷16 gives the same answer as 13×61

1×63×1=6÷33÷3=21=2
