Question

3 х 17 – 4 х 12 51 : 3 + 37 80 – 48 : 2 60 – 84 : 7 36 : 12 75 : 25

Answer 1

3*17-4*12=51-48=3;
51:3+37=17+37=54;
80-48:2=80-24=56;
60-84:7=60-12=48;
36:12=3; 75:25=3

Answer 2

1)51х-4х•417+37
51х-1668+37
-1617х+37

2)80-48,260-12
68-48,260
4408,65

3)36,1275•1,25

Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). Here's the step-by-step breakdown:

1. Start with the multiplications and divisions from left to right: 3 x 17 = 51 4 x 12 = 48 51 / 3 = 17 37 / 80 = 0.4625 (rounded to four decimal places) 48 / 2 = 24 60 / 84 ≈ 0.7143 (rounded to four decimal places) 36 / 12 = 3 75 / 25 = 3

2. Now, we have: 17 - 24 + 0.4625 - 0.7143 + 3 - 17

3. Perform the remaining additions and subtractions from left to right: 17 - 24 = -7 -7 + 0.4625 = -6.5375 -6.5375 - 0.7143 = -7.2518 -7.2518 + 3 = -4.2518 -4.2518 - 17 ≈ -21.2518

So, the final result is approximately -21.2518.
