Question

what fraction is 270 gram of 3 kilometre

Answer 1

I don't think so that it is 3 kilometre maybe 3 kg..
Convert 3 kg into gm..
We get 3 × 1000 = 3000 gm
Divide 270 gm by 3000 gm
We get,, 270/3000 = 9/100
Hence, 9/100 is the required fraction

But if we think hypothetically or practically, gram with kilometre is not possible

Answer 2

Solution :-

It must be 3 kilograms instead of 3 kilometers.

To find the required fraction, first we have to convert the kilograms into grams.

3 kg = 3*1000 grams
= 3000 grams.

Now,
Required fraction = 270 grams/3000 grams = 27/300

Find the H.C.F. of 27 and 300 and then simplify it to the lowest fraction. 

27 = 1, 3, 9 and 27

300 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150 and 300

So, 3 is the only common factor of 27 and 300. Hence, H.C.F. of 27 and 300 is 3

So, dividing both the numbers by 3, we will get.

⇒ (27÷3)/(300÷3)
⇒ 9/100
