Question

( 1 1/5 + 2 3/10): 1/2 + (6 3/44 - 2 2/3): 1 1/6 ответьте пожалуйста

Answer 1

( 1 1/5 + 2 3/10): 1/2 + (6 3/44 - 2 2/3): 1 1/6
1) 1 1/5+2 3/10=3 2+3/10=3 5/10=3 1/2=3,5
2) 6 3/44 - 2 2/3= 3 53/132
3) 3.5:1/2=3.5:0.5=7
4)3 53/132:1 1/6= 2 141/154
5)7+2 141/154=9 141/154

Answer 2

$(1 \frac{1}{5} + 2 \frac{3}{10} ) \div \frac{1}{2} + (6 \frac{3}{44} - 2 \frac{2}{3} ) \div 1\frac{1}{6} = 9 \frac{141}{154}$

$1) \: 1 \frac{1}{5} + 2 \frac{3}{10} = \frac{6}{5} + \frac{23}{10} = \frac{6 \times 2}{5 \times 2} + \frac{23}{10} = \frac{12}{10} + \frac{23}{10} = \frac{35}{10}$
$2) \: \frac{35}{10} \div \frac{1}{2} = \frac{ 35}{10} \times \frac{2}{1} = \frac{35 \times 2}{10 \times 1} = \frac{35 \times 1}{5 \times 1} = \frac{35}{5} = 7$
$3) \: 6 \frac{3}{44} - 2 \frac{2}{3} = \frac{267}{44} - \frac{8}{3} = \frac{267 \times 3}{44 \times 3} - \frac{8 \times 44}{3 \times 44} = \frac{801}{132} - \frac{352}{132} = \frac{449}{132}$

$4) \: \frac{449}{132} \div 1 \frac{1}{6} = \frac{449}{132} \div \frac{7}{6} = \frac{449}{132} \times \frac{6}{7} = \frac{449 \times 6}{132 \times 7} = \frac{449 \times 1}{22 \times 7} = \frac{449}{154}$

$5) \: 7 + \frac{449}{154} = \frac{7}{1} + \frac{449}{154} = \frac{7 \times 154}{1 \times 154} + \frac{449}{154} = \frac{1078}{154} + \frac{449}{154} = \frac{1527}{154} = 9 \: \frac{141}{154}$
