Question

A)5/3*(1+1/2)+17/4:(1+7/10)

VA ROG SA MA AJUTATI

Answer 1

$a) \: \frac{5}{3} \times (1 + \frac{1}{2}) + \frac{17}{4} \div (1 + \frac{7}{10}) = 5$
$(1 + \frac{1}{2}) = \frac{3}{2}$
$(1 + \frac{7}{10}) = \frac{17}{10}$
$\frac{17}{10} = \frac{10}{17}$
$\frac{5}{3} \: \: \frac{3}{2} = 3 \div 3 = 1 = \frac{1}{2}$
$=$
$\frac{17}{4} \: \: \: \frac{10}{17} = 17 \div 17 = 1 = \frac{1}{4} = 10 \div 2 = 5 = 4 \div 2 = 2 = \frac{1}{2} \times 5 = 5 \times 1 = 5 = \frac{5}{2}$
$\frac{5}{2} + \frac{1}{2} \times 5 = 5 = \frac{5}{2} = \frac{5}{2} + \frac{5}{2} = 5$
