There are probably several ways to do this question.
This is the first one that came to mind. Is it easier to make 2/5 an equivalent in terms of 200 or is it easier to make 7/200 an equivalent in terms of 5. I don't like fractions or decimals, so let's go with the first one.
To make it easier to see, I'm going to re-write the equation
2 = x
--- -----
5 200
200/5 = 40 so we are multiplying 5 by 40 to get 200 in the denominator. So we have to multiply 2 by 40 in the numerator to get the equivalent fraction.
Now we have
2 80
--- = -----
5 200
Since 80/200 is equal to 2/5, we can now compare 80/200 with 7/200.
Back to the original question, 7/200 is less than 80/200.
Sorry for being so verbose. I just wanted to explain all my steps;)
Good luck,
Paul
