Question

Exercitiile 1,2 si 3 va rog ! Va dau ce vreti voi !!!! plz

Answer 1

1)

2019 - (180 : 15 x 2 + 183) : 9

= 2019 - (24 + 183) : 9

= 2019 - 207 : 9

= 2019 - 23

= 1996

2)

5/10  6/12  7/14

55/56  45/45  35/34

10/50  15/50  16/50

3)

m + 5 + n + 7 + p + 9 = 31

m + n + p = 31 - 21 = 10

2018 + (m+n+p) = 2018 + 10 = 2019

Answer 2

1)

2019-(180:15*2+183):9=

2019-(12*2+183):9=

2019-(24+183):9=

2019-207:9=

2019-23= 1996

2)a)

$\frac{1}{2} \: \frac{2}{4} \: \frac{3}{6} \: \frac{4}{8} \: \frac{5}{10} \: \frac{6}{12} \: \frac{7}{14}$

b)

$\frac{95}{100} \: \frac{85}{89} \: \frac{75}{78} \: \frac{65}{67} \: \frac{55}{56} \: \frac{45}{45} \: \frac{35}{34}$

c)

$\frac{1}{50} \: \frac{4}{50} \: \frac{5}{50} \: \frac{9}{50} \: \frac{14}{50} \: \frac{23}{50} \: \frac{37}{50}$

3)m+5+n+7+p+9=31

m+n+p=31-5-7-9

m+n+p=10

2018+m+n+p=2018+10=2028
