Second -- Copy and paste your problems into www.google.com and see what happens.

1.
2 / 5 = 2 * 2 / ( 5 * 2 ) = 4 / 10
4 2/5 = 4 + 2 / 5 = 4 + 4 / 10 = 4 * 10 / 10 + 4 / 10 = 40 / 10 + 4 / 10 = 44 / 10
1 7/10 = 1 + 7 / 10 = 10 / 10 + 7 / 10 = 17 / 10
4 2/5 - 1 7/10 = 44 / 10 - 17 / 10 = 27 /10 = 20 / 10 + 7 / 10 = 2 7/10
2.
5 2/3 = 5 + 2 / 3 = 5 * 3 / 3 + 2 / 3 = 15 / 3 + 2 / 3 = 17 / 3
2 1/3 = 2 + 1 / 3 = 2 * 3 * 3 + 1 / 3 = 6 / 3 + 1 / 3 = 7 / 3
5 2/3 - 2 1/3 = 17 / 3 - 7 / 3 = 10 / 3
10 / 3 = ( 9 + 1 ) / 3 = 9 / 3 + 1 / 3 = 3 1/3
OR
5 2/3 - 2 1/3 = 5 - 2 + 2 / 3 - 1 / 3 = 3 + 1 / 3 = 3 1/3
2 / 5 = 2 * 2 / ( 5 * 2 ) = 4 / 10
4 2/5 = 4 + 2 / 5 = 4 + 4 / 10 = 4 * 10 / 10 + 4 / 10 = 40 / 10 + 4 / 10 = 44 / 10
1 7/10 = 1 + 7 / 10 = 10 / 10 + 7 / 10 = 17 / 10
4 2/5 - 1 7/10 = 44 / 10 - 17 / 10 = 27 /10 = 20 / 10 + 7 / 10 = 2 7/10
2.
5 2/3 = 5 + 2 / 3 = 5 * 3 / 3 + 2 / 3 = 15 / 3 + 2 / 3 = 17 / 3
2 1/3 = 2 + 1 / 3 = 2 * 3 * 3 + 1 / 3 = 6 / 3 + 1 / 3 = 7 / 3
5 2/3 - 2 1/3 = 17 / 3 - 7 / 3 = 10 / 3
10 / 3 = ( 9 + 1 ) / 3 = 9 / 3 + 1 / 3 = 3 1/3
OR
5 2/3 - 2 1/3 = 5 - 2 + 2 / 3 - 1 / 3 = 3 + 1 / 3 = 3 1/3
