Answer 3

Let's solve each of these mathematical expressions step by step:

1. 1500:(500—200×2) First, calculate the result inside the parentheses: 500 - 200 × 2 = 500 - 400 = 100 Now, divide 1500 by 100: 1500 ÷ 100 = 15

2. 1500×(500—200):2 Again, start by calculating inside the parentheses: 500 - 200 = 300 Then, divide 300 by 2: 300 ÷ 2 = 150 Finally, multiply 1500 by 150: 1500 × 150 = 225,000

3. 3546—283×4+819 First, perform the multiplication and subtraction inside the parentheses: 283 × 4 = 1132 Then, subtract 1132 from 3546: 3546 - 1132 = 2414 Finally, add 819 to 2414: 2414 + 819 = 3233

4. 1254+654:5—967 Start by performing the division and subtraction: 654 ÷ 5 = 130.8 (rounded to one decimal place) Now, subtract 967 from 1254: 1254 - 967 = 287 Finally, add 287 to 130.8: 287 + 130.8 = 417.8 (rounded to one decimal place)

So, the results are as follows:

1. 1500:(500—200×2) = 15
2. 1500×(500—200):2 = 225,000
3. 3546—283×4+819 = 3233
4. 1254+654:5—967 = 417.8
