Question

simplify (2*3÷4+1*5÷6) +2*1÷5 of 3*1÷3​

Answer 1

Answer:

$( \frac{2 \times 3}{4} + \frac{1 \times 5}{6} ) + \frac{2 \times 1}{5} \times \frac{3 \times 1}{3} \\ = ( \frac{6}{4} + \frac{5}{6} ) + \frac{2}{5} \times 1 \\ = ( \frac{6 \times 3}{4 \times 3} + \frac{5 \times 2}{6 \times 2} ) + \frac{2}{5} \\ = \frac{18 + 10}{12} + \frac{2}{5} \\ = \frac{28}{12} + \frac{2}{5} \\ = \frac{28 \times 5}{12 \times 5} + \frac{2 \times 12}{5 \times 12} \\ = \frac{ 140+ 24}{60} \\ = \frac{164}{60} \\ = \frac{164 \div 4}{60 \div 4} \\ = \frac{41}{15} \\ = 2 \frac{11}{15}$
