Question

(-2,8)*(-3,5)*(-2 2/3)

Answer 1

(-2,8) · (-3,5) · (-2 2/3) = -26 2/15

1) (-2,8) · (-3,5) = 9,8

2) 9,8 · (-2 2/3) = 98/10 · (-8/3) = -(98·4)/(5·3) = -392/15 = -26 2/15

Ответ: -26 целых 2/15.

Answer 2

It looks like you're trying to perform multiplication on three different numbers written in a mixed numeral form. Let's break it down step by step:

1. (-2, 8) = -2 + 8/10 = -2.8
2. (-3, 5) = -3 + 5/10 = -2.5
3. (-2 2/3) = -2 + 2/3 = -2.666...

Now, let's multiply these three numbers:

(-2.8) * (-2.5) * (-2.666...) ≈ 18.67

Please note that the result is an approximation due to the repeating decimal in the last number. If you need a more precise answer, you might want to work with the exact fractions or decimals without rounding.
