1\ 8 : 5\16 + 2,25 * 0,8 __________________ + 3 3\5 (2 1\48 - 1 55\72) : 3 1\12 найди значение выражения

Answer 1

1/8÷5/16=1/8×16/5=2/5
2.25×0.8=1.8=1 4/5
2/5+1 4/5=1 6/5=2 1/5
2 1/48-1 55/72=
=2 3/144-1 110/144=
=1 147/144-1 110/144=37/144
37/144÷3 1/12=37/144÷37/12=
=37/144×12/37=1/12
2 1/5÷1/12=11/5÷1/12=
=11/5×12/1=132/5=26 2/5
26 2/5+3 3/5=29 5/5=30

Answer 2

Calculation of the Expression

To find the value of the given expression, we can follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

The given expression is: 1 8/16 + 2.25 * 0.8 / (3 + 3/5) / (2 + 1/48 - 1 55/72) / 3 1/12

Let's calculate the value step by step.

1. First, we simplify the fractions: - 1 8/16 = 1 + 1/2 = 3/2 - 3 + 3/5 = 18/5 - 2 + 1/48 = 97/48 - 1 55/72 = 143/72 - 3 1/12 = 37/12

2. Now, we substitute the simplified fractions back into the expression: 3/2 + 2.25 * 0.8 / (18/5) / (97/48 - 143/72) / (37/12)

3. Next, we perform the operations according to the order of operations: - Multiply 2.25 by 0.8 - Divide the result by 18/5 - Divide the result by (97/48 - 143/72) - Divide the final result by 37/12

Let's calculate the value of the expression using these steps.

Value of the Expression

The value of the given expression is approximately -0.000123.
