Question

Найдите значения выражений
11/15*25/33+1 3/4 2 1/16-2/3*7/12
1/2*1 2/3:10 (1 - 1/2):(1/2 - 1/3)

Answer 1

11/15*25/33+7/4
1) 11/15*25/33=5/9
2) 5/9+7/4=36/12=3
1/2*1 2/3:10
1)1/2*5/3=5/6
2)5/6:10/1=5/6*1/10=1/12
2 1/16-2/3*7/12
2/3*7/12=7/18
2 1/16-7/18=33/16-7/18=482/288=241/144
(1-1/2):(1/2-1/3)
1-1/2=2/2-1/2=1/2
1/2-1/3=1/6
1/2:1/6=1/2*1/6=3
