Answer 1

Ответ:

Пошаговое объяснение:

1 1/2×(-5)×(-2/3)=3/2*(-2/3)*(-5)=5

-1 3/7×(-9)×(-7/10)=-10/7*(-7/10)*(-9)=-9

4x×(-3)=-12х

(-R)×5×(-3)​=15R

Answer 2

It seems like you have an expression with multiple multiplications and fractions. Let's break it down step by step:

1. 1 1/2 × (-5) × (-2/3): First, convert the mixed number to an improper fraction: 1 1/2 = 3/2 Now, multiply the fractions: (3/2) × (-5) × (-2/3) = (-15/2) × (-2/3) When you multiply two negative fractions, the negatives cancel out: (-15/2) × (-2/3) = (15/2) × (2/3) Now, multiply the fractions: (15/2) × (2/3) = 15/3 = 5

2. 1 3/7 × (-9) × (-7/10): First, convert the mixed number to an improper fraction: 1 3/7 = 10/7 Now, multiply the fractions: (10/7) × (-9) × (-7/10) When you multiply two negative fractions, the negatives cancel out: (10/7) × (-9) × (-7/10) = (10/7) × (9/10) Now, multiply the fractions: (10/7) × (9/10) = (90/70)

3. 4x × (-3) × (-R) × 5 × (-3): Simply multiply all the numbers together: 4x × (-3) × (-R) × 5 × (-3) = -4xR × (-15)

Now, let's put it all together:

5 + (90/70) - 4xR × (-15)

You can simplify further if you have more information about the value of x and R.
