Question

1) 2/3:(-2); (-3/4):1 1/2; ​СРОЧНО!!!

Answer 1

2/3 : (-2) = 2/3 * (-1/2) = -1/3

-3/4 : 1 1/2 = -3/4 : 3/2 = -3/4 * 2/3 = -1/2 = -0,5

Answer 2

It seems like you have provided two ratios:

1. 2/3 : -2
2. -3/4 : 1 1/2

To compare these ratios, let's first convert the second ratio to a fractional form. To do that, we need to convert the mixed number "1 1/2" to an improper fraction.

1 1/2 can be written as (2 * 1) + 1 = 3. So, the second ratio becomes:

-3/4 : 3

Now, to compare these ratios, we can cross-multiply and see which ratio is greater:

1. Cross-multiplying the first ratio:

(2 * -2) = -4

2. Cross-multiplying the second ratio:

(-3 * 3) = -9

Comparing the cross-products:

-4 < -9

Therefore, the second ratio (-3/4 : 1 1/2) is greater than the first ratio (2/3 : -2).
