One way to do this is to find the least common denominator for the 4 fractions and rewrite them accordingly.
The denominators are 5, 7, 9, and 6. Multiply them to get the product 1890. Use this as the denominator.
9/5 = ?/1890. To find value of ? cross-multiply to find 9*1890 = 5*? Divide both sides by 5 to see ? = 3402.
Do the same for the other 3 fractions so that
2/7 = ?/1890 ==> ? = 540
7/9 = ?/1890 ==> ? = 1470 and
5/6 = ?/1890 ==> ? = 1575
Now compare the rewritten fractions: 3402/1890, 540/1890, 1470/1890, and 1575/1890
Knowing this, it is simple to see the ascending order of the given fractions is 2/7, 7/9, 5/6, and 9/5
