Question

знайти значення віразу (14 1/8 - 10 3/5) : 1,41

Answer 1

$(14 \frac{1}{8} - 10 \frac{3}{5} ) \div 1 \frac{41}{100} = 2 \frac{1}{2}$

$14 \frac{1}{8} - 10 \frac{3}{5} = 3 \frac{21}{40}$

$3 \frac{21}{40} \div 1 \frac{41}{100} = \frac{141}{40} \times \frac{100}{141} = \frac{5}{2} = 2 \frac{1}{2}$
