Question

1) -1/8*(8*(-3/11))2) 4/5*3 1/3*(-7 1/2)​

Answer 1

Ответ:

1. -1/8(24/11)=

3/11

2. 4/5×3×1/3(-15/2)=

-2×3=-6

Answer 2

Let's solve these two expressions step by step:

1. -1/8 * (8 * (-3/11)): First, simplify the expression inside the parentheses: 8 * (-3/11) = -24/11 Now, multiply this result by -1/8: -1/8 * (-24/11) = 24/88 To simplify further, you can reduce the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 8: (24/8) / (88/8) = 3/11

So, the result of the first expression is 3/11.

2. 4/5 * 3 1/3 * (-7 1/2): First, convert the mixed numbers to improper fractions: 3 1/3 = (3 * 3 + 1)/3 = 10/3 -7 1/2 = (-7 * 2 + 1)/2 = -15/2

Now, multiply the fractions: (4/5) * (10/3) * (-15/2)

To multiply fractions, you can multiply the numerators together and the denominators together: (4 * 10 * -15) / (5 * 3 * 2)

Now, calculate the numerator and denominator separately: Numerator = 4 * 10 * -15 = -600 Denominator = 5 * 3 * 2 = 30

So, the result of the second expression is -600/30, which can be further simplified by dividing both the numerator and denominator by their GCD, which is 30: (-600/30) / (30/30) = -20

So, the result of the second expression is -20.
