Question

0,9×3+3/4×3-1,15×3сколько будет???

Answer 1

0.9*3=2.7
3/4*3=9/4=2.25
2.7+2.25=4.95
1.15*3=3.45
4.95-3.45=1.5

Answer 2

0,9×3+3/4×3-1,15×3 = 3*(0,9 + 0,75 - 1,15) = 3*0,5=1,5

Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets (not present in this expression)
2. Exponents/Orders (not present in this expression)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression is: 0.9 × 3 + 3/4 × 3 - 1.15 × 3

Let's calculate it step by step:

1. 0.9 × 3 = 2.7
2. 3/4 × 3 = 0.75 × 3 = 2.25
3. 1.15 × 3 = 3.45

Now, the expression becomes: 2.7 + 2.25 - 3.45

4. Add the numbers together: 2.7 + 2.25 = 4.95

Finally, subtract: 4.95 - 3.45 = 1.5

So, the result of the expression is 1.5.
