Question

- 16 1/20 + ( - 6 1/25) = 1/20 и 1/25 - это дроби

Answer 1

-16 5/100 + ( -6 4/100 ) = -22 9/100

Answer 2

To add and subtract fractions, we need to find a common denominator for both fractions. The common denominator for 20 and 25 is 100, so we'll rewrite the fractions with this denominator.

First, let's convert the mixed numbers to improper fractions:

• 16 1/20 = (16 * 20 + 1)/20 = (321/20)
• -6 1/25 = (-6 * 25 + 1)/25 = (-151/25)

Now, let's add them:

(321/20) + (-151/25) = (321 * 5)/(20 * 5) + (-151 * 4)/(25 * 4) = 1605/100 + (-604/100) = (1605 - 604)/100 = 1001/100

Now, let's simplify the result. Since the numerator (1001) is greater than the denominator (100), we can write it as a mixed number:

1001/100 = 10 1/100

So, the result of the expression is 10 1/100, which is equivalent to the fraction 1/20.
