Answer 2

Calculation of Expressions

Let's solve the given expressions step by step:

a) -15/17:3

To divide -15/17 by 3, we need to divide the numerator (-15) by the denominator (17) and then divide the result by 3.

-15/17 ÷ 3 = -15/17 * 1/3 = (-15 * 1) / (17 * 3) = -15/51

Therefore, -15/17 divided by 3 is equal to -15/51.

b) -8:2/3

To divide -8 by 2/3, we need to divide the numerator (-8) by the fraction 2/3. To divide by a fraction, we multiply by its reciprocal.

-8 ÷ (2/3) = -8 * (3/2) = (-8 * 3) / 2 = -24/2 = -12

Therefore, -8 divided by 2/3 is equal to -12.

c) -27:(-18)

To divide -27 by -18, we need to divide the numerator (-27) by the denominator (-18).

-27 ÷ (-18) = 27/18 = 3/2

Therefore, -27 divided by -18 is equal to 3/2.

Summary

The solutions to the given expressions are as follows:

a) -15/17:3 = -15/51 b) -8:2/3 = -12 c) -27:(-18) = 3/2
