Question

Найдите значение выражения -6-(-0,36) = 3 5/12* 0,24= 10 2/7:1 11/21= ответы должны быть: -0,24,0,82 и 6,75

Answer 1

-6 - ( -0,36 ) = - 6 + 0,36 = -5,64
3 5/12 × 0,24 = 41/12 × 6/25 = 41/50 = 0,82
10 2/7 ÷ 1 11/21 = 72/7 × 21/32 = 6¾ = 6,75

Answer 2

-6 - (-0,36) = -6 + 0,36 = -5,64
3 5/12 • 0,24 = 41/12 • 6/25 = 41/2 • 1/25 = 41/50 = 0,82
10 2/7 : 1 11/21 = 72/7 : 32/21 = 72/7 • 21/32 = 9 • 3/4 = 27/4 = 6,75

Answer 3

Calculating the Expression

To find the value of the given expression, we'll follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to solve it step by step.

1. Solving -6-(-0,36): - The expression -6-(-0,36) simplifies to -6 + 0,36. - This equals -5,64.

2. Solving 3 5/12* 0,24: - The expression 3 5/12* 0,24 simplifies to 41/12 * 6/25. - This equals 246/300. - Simplifying further, this equals 41/50.

3. Solving 10 2/7:1 11/21: - The expression 10 2/7:1 11/21 simplifies to 72/7 ÷ 32/21. - This equals 72/7 * 21/32. - This further simplifies to 1512/224. - Simplifying the fraction, this equals 189/28. - Finally, this equals 6.75.

Conclusion

Therefore, the values of the given expression are: - -6-(-0,36) = -5,64 - 3 5/12* 0,24 = 41/50 - 10 2/7:1 11/21 = 6,75
