Question

Oblicz. ;

a)(4-11/4 : 1 9/16) ( - 15 5/8)

c)4/5 - ( 1,2 x 5/12 - 0,8) : (-1/8)

Oblicz. ;

-(-(-(-5))) + ( -4) x (8-12)-(-(-3)) x (-12) : (-(-6))

Answer 1

a) = ( 5/4 : 25/16 )* (-125/8) = (5/4 * 16/25 ) * -125/8 = - 5/2

b ) =4/5 - ( 6/5 * 5/12 - 4/5 ) * - 5/9 = 4/5 - ( 5/10 - 8/10 ) * -5/9 = 4/5 - (- 3/10 * - 5/9 ) = 4/5 - 15/9057/90

c ) = -5 + 16 - 6 = 5

Answer 2

a) = ( 5_4 : 25_16 )* (-125_8) = (5_4 * 16_25 ) * -125_8 = - 5_2

b ) =4_5 - ( 6_5 * 5_12 - 4_5 ) * - 5_9 = 4_5 - ( 5_10 - 8_10 ) * -5_9 = 4_5 - (- 3_10 * - 5_9 ) = 4_5 - 15_9057_90

c ) = -5 + 16 - 6 = 5
