1 and 2/5 minus 7/8 is 21/40.
1 and 2/5 is equivalent to 7/5, giving you 7/5 minus 7/8.
Multiply 7/5 by 8/8 to get 56/40, then 7/8 by 5/5 to get 35/40.
56/40 minus 35/40 gives you 21/40.
1 2/5 - 7/8 = 21/40

1 and 2/5 is equivalent to 7/5, giving you 7/5 minus 7/8

Multiply
 
7/5 * 8/8 = 56/40,

then 7/8 * 5/5 = 35/40

56/40 - 35/40 = 21/40.
