22/7*21/46=33/23=1 целая 10/23

Answer 2

To solve the expression (9 - 8/3) * (15/7) * (21/46), let's break it down step by step:

Step 1: Simplify the expression within the parentheses: 9 - 8/3 = 27/3 - 8/3 = 19/3

Step 2: Multiply the fractions: (19/3) * (15/7) * (21/46)

To multiply fractions, you multiply the numerators together and the denominators together: (19 * 15 * 21) / (3 * 7 * 46)

Step 3: Simplify the fraction, if possible: 19 * 15 * 21 = 5985 3 * 7 * 46 = 966

The expression simplifies to: 5985/966

However, if you meant to write it as (9 - 8)/(3 * (15/7) * (21/46)), the steps would be as follows:

Step 1: Simplify the expression within the parentheses: 9 - 8 = 1

Step 2: Multiply the fractions: 1 / (3 * (15/7) * (21/46))

To multiply fractions, you multiply the numerators together and the denominators together: 1 / (3 * 15 * 21) / (7 * 46)

Step 3: Simplify the fraction, if possible: 3 * 15 * 21 = 945 7 * 46 = 322

The expression simplifies to: 1 / (945/322)

To divide by a fraction, you multiply by its reciprocal: 1 * (322/945)

The expression further simplifies to: 322/945
