Question

4*(-4/7-2/3)-5/12:35/4

Answer 1

4 * (- 26/21) -5/12 * 4/35 =- 104/21 - 1/3 * 1/7 = - 104/21 - 1/21 = -5

Answer 2

1)-4/7-2/3=-12/21-14/21=-26/21

2)4*(-26/21)=-104/21

3)5/12:35/4=1/21

4)-104/21-1/21=-105/21=-5

Answer 3

Let's break down the expression step by step:

1. $4 \times \left(-\frac{4}{7} - \frac{2}{3}\right) - \frac{5}{12} \div \frac{35}{4}$

2. Find the common denominator for the fractions in the parentheses (which is 21):

   $4 \times \left(-\frac{12}{21} - \frac{14}{21}\right) - \frac{5}{12} \div \frac{35}{4}$

3. Combine the fractions in the parentheses:

   $4 \times \left(-\frac{26}{21}\right) - \frac{5}{12} \div \frac{35}{4}$

4. Multiply 4 by $-\frac{26}{21}$:

   $-\frac{104}{21} - \frac{5}{12} \div \frac{35}{4}$

5. Now, let's simplify the division of fractions by multiplying the numerator by the reciprocal of the denominator:

   $-\frac{104}{21} - \frac{5}{12} \times \frac{4}{35}$

   $-\frac{104}{21} - \frac{1}{3}$

6. To combine the fractions, find a common denominator (which is 63):

   $-\frac{312}{63} - \frac{21}{63}$

7. Combine the fractions:

   $-\frac{333}{63}$

8. Simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 3:

   $-\frac{111}{21}$

9. Finally, simplify the fraction further:

   $-\frac{37}{7}$

Therefore, the result of the expression $4 \times \left(-\frac{4}{7} - \frac{2}{3}\right) - \frac{5}{12} \div \frac{35}{4}$ is $-\frac{37}{7}$.
