Question

Cine stie va rog sa ma ajutati .Cu explicați.​

Answer 1

$\it{a)2.4 - 4.2 - 3.2 \div \frac{4}{5} = 2.4 - 4.2 - 3.2 \div 0.8 = }$

$\it{2.4 - 4.2 - 4 = - 1.8 - 4 = - 5.8}$

$\it{b)4.5 + \frac{31}{10} \times 2.6 = 4.5 + 3.1 \times 2.6 = }$

$\it{4.5 + 6.2 = 10.7}$

$\it{c) 34.5 + 9.11 - 9.2 \div 6.4 + 3.1(6) = 34.5 + 9.11 - 1.4375 + 3.1(6) = }$

$\it{ - 1.4375 + \frac{316 - 31}{90} = - \frac{23}{16} + \frac{285}{90} = - \frac{23}{16} + \frac{19}{6} = \frac{83}{48} }$
