Question

А) -0,1и-5/7б) 4/5-5/6

Answer 1

-0,1 > -5/7
4/5 - 5/6 = 0.3333...

Answer 2

а) To subtract two fractions, we need to find a common denominator and then subtract the numerators. The common denominator for -0.1 and -5/7 is 10.

First, let's convert -0.1 to a fraction: -0.1 = -0.1/1 = -1/10

Now, we can subtract the fractions: -1/10 - (-5/7) = -1/10 + 5/7

To find a common denominator for 10 and 7, we multiply them together: 10 * 7 = 70

Now, we can rewrite the fractions with the common denominator: -1/10 + 5/7 = -7/70 + 50/70

Finally, subtract the numerators: -7/70 + 50/70 = (50 - 7)/70 = 43/70

Therefore, the result of -0.1 - (-5/7) is 43/70.

b) To subtract 4/5 from 5/6, we also need to find a common denominator and then subtract the numerators.

The common denominator for 5/6 and 4/5 is 30.

Rewriting the fractions with the common denominator: 5/6 - 4/5 = 25/30 - 24/30

Now, subtract the numerators: 25/30 - 24/30 = (25 - 24)/30 = 1/30

Therefore, the result of 5/6 - 4/5 is 1/30.
