Question
In Exercises $51-58,$ perform the calculations on a calculator without rounding. Evaluate: (a) $2.2+3.8 \times 4.5 \quad$ (b) $(2.2+3.8) \times 4.5$
Step 1
According to the order of operations (BIDMAS/BODMAS), we should perform multiplication before addition. So, we first multiply 3.8 and 4.5, which gives us 17.1. Then, we add this result to 2.2. \[2.2 + 3.8 \times 4.5 = 2.2 + 17.1 = 19.3\] Show more…
