-Multiply the denominator and the middle number, then add nominator into that product. In this case, denominator = 5, middle number = 3 , nominator = 2. So, 5 times 3 is 15. Then add 15 to the nominator 2. Thus 15+2 = 17. The new nominator will be 17. After that, follow the simple arithmetic.
10- 17/5 =
10 - 3.4 = 6.6
