To solve this expression, we follow the order of operations (parentheses, exponents, multiplication and division from left to right, addition and subtraction from left to right):
(10/13 - 21/52 + 15/26) 39/7= (0.769230769 - 0.403846154 + 0.576923077) 5.57142857= (0.942307692) 5.57142857= 5.57142857 0.942307692= 5.25
Therefore, (10/13 - 21/52 + 15/26) * 39/7 = 5.25.
