Question

64*15-48*33 _ _ _ _ 5 * 4 -11*8 35 : 7 _ _ 3 18

Answer 1

$\frac{64}{5} * \frac{15 }{4} - \frac{48}{11 } * \frac{33}{8}$ = 

1) $\frac{64}{5} * \frac{15}{4} = \frac{16}{1} * \frac{3}{1}= 48$

2) $\frac{48}{11} * \frac{33}{8}= \frac{6}{1}* \frac{3}{1}=18$

3) 48-18=30

4)$\frac{35}{3} : \frac{7}{18} = \frac{5}{1} * \frac{6}{1} = 30$

5) 30/30=1

ответ: 1

Answer 2

1) 64*15-48*33 = 960 - 1584 = -624

2) (5*4 - 11*8) : (35/3 : 7/18) = (20-88) : (35/3 * 18/7) = -68 : (5*6) = -68/30 = -34/15
