Question

a)1/8:1/6+1/4*1 3/4

b)14,5-3,5*(1 3/5 + 0,4)

c)11*(-16+7)-(-9)

d)(4 1/3+5/6):(2-1/3)

Answer 1

1/8*6+1/4*4/7=6/8+1/7=3/4+1/7=21/28+4/28=25/28

14,5-3.5*(1,6+0,4)=14.5-3,5*2=14.5-7=7.5

11*(-9)+9=-99+9=-90

(13/3+5/6):(1 2/3)=(26/6+5/6):(5/3)=21/6*3/5=63/30=21/10=2,1

Answer 2

a)1/8:1/6+1/4*1 3/4=1/8*6+1/4*7/4=6/8+7/16=12/16+7/16=19/16=1 3/16

b)14,5-3,5*(1 3/5+0,4)=14,5-3,5*(1,6+0,4)=14,5-3,5*2=14,5-7=7,5

c)11*(-16+7)-(-9)=11*(-9)+9=-99+9=90

d)4 1/3+5/6):(2-1/3)=(4 2/6+5/6):1 2/3=5 7/6:1 2/3=37/6*5/3=185/18
