the question is actually asking How many 0.09s are there in 3.6

Well there are a great many, because 0.09 is a very little number.

10 lots of 0.09 are 10*0.09=0.9        3.6 is a lot bigger than that!

20 lots of 0.09 are 1.8                        3.6 is still bigger

infact

0.09 added to itself 40 times = 3.6

0.09*40=3.6

so that is why

3.6 divided by 0.09 = 40

If you multiplied both the numerator and the denominator of the fraction by 100,

the numerator becomes  360         and the denominator becomes  9.

Now, you have 360 ÷ 9, which is 40.

Does this help?
