Question

выполните действия 3/4*1/5 7/20*1 1/3 8*5/6 2/3:4/5 3/8:9 (3 1/3)³

Answer 1

3/4  *  1/5  = (3*1) / (4*5) = 3/20
7/20  *   1  1/3 = 7/20  *  4/3 =  (7*1)/(5*3) =7/15
8  *  5/6  = (8*5) / (1*6)  = (4*5)/(1*3) =20/3= 6   2/3
2/3  :  4/5  = 2/3  *  5/4 = (2*5)/(3*4)= (1*5)/(3*2)=5/6
3/8  :9   = 3/8    *  1/9 = (3*1)/(8*9) = (1*1)/ (8*3)= 1/24

(3  1/3 )³=  (10/3 ) ³ = 1000/27 =  37   1/27
