Exercise 12 Page 56

Remember that a÷ b is the same as ab.

False

Practice makes perfect

Consider the given equation. 91÷(- 7)-5=35÷ 7 +3 To determine whether this equation is true, false, or open, we need to simplify by following the order of operations.

91÷(- 7)-5? =35÷ 7 +3
91/(- 7)-5? =35/7+3
- 91/7-5? =35/7+3
- 13 -5 ? = 5+3
- 18≠8

Since the left-hand side and the right-hand side are not equal, the equation is false.
