Question

2,25:(1,5)-3/8*(-2,4)=

Answer 1

$2.25 \div (1.5) - \frac{3}{8} ( - 2.4) = 1.5 - \frac{3}{8} ( - \frac{12}{5} ) = \frac{3}{2} + \frac{3}{2} \times \frac{3}{5} = \frac{3}{2} + \frac{9}{10} = \frac{12}{5}$

Answer 2

To calculate the expression, let's break it down step by step:

1. Start with the division inside the parentheses: 1/5 = 0.2

2. Next, multiply this result by -3/8: 0.2 * (-3/8) = -0.075

3. Now, subtract this result from 2.25: 2.25 - (-0.075) = 2.325

So, 2.25:(1,5)-3/8*(-2,4) = 2.325

Answer 3

To calculate the expression "2.25:(1.5) - 3/8 * (-2.4)," 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 calculation:

1. First, perform the division inside the parentheses: 2.25 / 1.5 = 1.5

2. Now, let's calculate the remaining expression: 1.5 - (3/8) * (-2.4)

3. Calculate the multiplication inside the parentheses: (3/8) * (-2.4) = -0.9

4. Now, subtract the result from step 3 from the result of step 2: 1.5 - (-0.9) = 1.5 + 0.9 = 2.4

So, the value of the expression "2.25:(1.5) - 3/8 * (-2.4)" is equal to 2.4.
