Question

2/3*(-3/8m+6)-3/7*(28-7/12m) решить

Answer 1

Ответ:

1/4m+4/1-12+1/4m=4-12=-8

Answer 2

To solve the given expression, let's simplify it step by step:

1. Distribute the terms inside the parentheses: 2/3 * (-3/8m + 6) - 3/7 * (28 - 7/12m)

   Simplified form: -2/8m + 4 - 12/7 + 1/2m

2. Combine like terms: (-2/8m + 1/2m) + (4 - 12/7)

   Simplified form: (-1/4m + 1/2m) + (4 - 12/7)

3. Simplify the fractions with a common denominator: (-1/4m + 2/4m) + (28/7 - 12/7)

   Simplified form: (1/4m) + (16/7)

4. Combine the fractions: (1/4m) + (16/7)

   To combine the fractions, we need a common denominator, which is 4m * 7 = 28m.

   Multiplying the first fraction by 7/7 and the second fraction by 4m/4m, we get:

   (7/28m) + (64m/28m)

   Simplified form: (7 + 64m)/(28m)

So the solution to the expression 2/3*(-3/8m+6)-3/7*(28-7/12m) is (7 + 64m)/(28m).
