We are given 7+7 divided by 7 +7 x 7 -7 = ? Rewritten, this expression becomes(7+7) ÷ (7 + (7 x 7) -7)
When we clear the first parenthesis, we get 14 ÷ (7 + (7 x 7) -7)
We then complete the multiplication within the parenthesis (7 x 7), which is 49
Our expression is then 14 ÷ (7 + (49) -7);
we then combine terms which yields 14 ÷ 49,
we then divided the numerator and denominator by 7, yields 2/7
