Calculate or simplify the expression $$ 4/3-1/7-12+9/7 $$.
Calculate the value by following steps:
- step0: Calculate:
  $$\frac{4}{3}-\frac{1}{7}-12+\frac{9}{7}$$
- step1: Reduce fractions to a common denominator:
  $$\frac{4	imes 7}{3	imes 7}-\frac{3}{7	imes 3}-\frac{12	imes 3	imes 7}{3	imes 7}+\frac{9	imes 3}{7	imes 3}$$
- step2: Multiply the numbers:
  $$\frac{4	imes 7}{21}-\frac{3}{7	imes 3}-\frac{12	imes 3	imes 7}{3	imes 7}+\frac{9	imes 3}{7	imes 3}$$
- step3: Multiply the numbers:
  $$\frac{4	imes 7}{21}-\frac{3}{21}-\frac{12	imes 3	imes 7}{3	imes 7}+\frac{9	imes 3}{7	imes 3}$$
- step4: Multiply the numbers:
  $$\frac{4	imes 7}{21}-\frac{3}{21}-\frac{12	imes 3	imes 7}{21}+\frac{9	imes 3}{7	imes 3}$$
- step5: Multiply the numbers:
  $$\frac{4	imes 7}{21}-\frac{3}{21}-\frac{12	imes 3	imes 7}{21}+\frac{9	imes 3}{21}$$
- step6: Transform the expression:
  $$\frac{4	imes 7-3-12	imes 3	imes 7+9	imes 3}{21}$$
- step7: Multiply the numbers:
  $$\frac{28-3-12	imes 3	imes 7+9	imes 3}{21}$$
- step8: Multiply the terms:
  $$\frac{28-3-252+9	imes 3}{21}$$
- step9: Multiply the numbers:
  $$\frac{28-3-252+27}{21}$$
- step10: Calculate:
  $$\frac{-200}{21}$$
- step11: Rewrite the fraction:
  $$-\frac{200}{21}$$
La expresión $$ \frac{4}{3}-\frac{1}{7}-12+\frac{9}{7} $$ se simplifica a $$ -\frac{200}{21} $$ o $$ -9\frac{11}{21} $$ o $$ -9.5\dot{5}2380\dot{9} $$.
La expresión simplifica a $$ -\frac{200}{21} $$ o $$ -9\frac{11}{21} $$ o $$ -9.5\dot{5}2380\dot{9} $$.
