Set up a proportion:
5/7/10 = 1/x
Cross multiply:
5/7x = 10
Divide 5/7 to both sides or multiply by its reciprocal, 7/5:
x = 10 * 7/5
x = 70/5
x = 14
So there were 14 muffins, now subtract 10 from it to find out how many are left.
14 - 10 = 4
So there are 4 muffins left.
5/7/10 = 1/x
Cross multiply:
5/7x = 10
Divide 5/7 to both sides or multiply by its reciprocal, 7/5:
x = 10 * 7/5
x = 70/5
x = 14
So there were 14 muffins, now subtract 10 from it to find out how many are left.
14 - 10 = 4
So there are 4 muffins left.

10 muffins is 5/7 of your muffins.
You had 7/7 of your muffins at the start, which is 7/5 times more.
Hence you had 10*7/5=14 muffins at the beginning.
Thus you have 14-10=4 muffins left !
