Answer 1

Ответ:

a)

$9.72 \div ( \frac{9}{2} - 2.5) = \\ 9.75 \div (4.5 - 2.5) = \\ 9.75 \div 2 = 4.875$

b)

$15.96 \div ( \frac{9}{25} + 2.64) = \\ 15.96 \div (0.36 + 2.64) = \\ 15.96 \div 3 = 5.32$

c)

$( \frac{21}{5} - 3.93) \div 2 = \\ (4.2 - 3.93) \div 2 = \\ 0.27 \div 2 = 0.135$

d)

$( \frac{31}{5} - 3.96) \div 4 = \\ (6.2 - 3.96) \div 4 = \\ 2.24 \div 4 = 0.56$
