Question

jak w załaczniku chodzi o zadanie 1 (prosze o dokladne rozwiazania)

Answer 1

a)

=1*0,09=0,09

b)

=√(5/4)²-1 + √1 7/9=√25/16+√16/9=5/4+4/3=

=15/12+16/12=31/12=2 7/12

c)

=35/10*2/5+7/25:7/10=7/5+7/25*10/7=7/5+2/5=9/5=1 4/5

d)

6 3/7-40/7*18/10  / 1:(3/6+1/6)=

=6 3/7-72/7  / 1:4/6= 45/7-72/7 /1*6/4=

=-27/7 / 6/4=-27/7 :6/4=-27/7*4/6=-36/7=-5 1/7

e)

=[(5 1/9-1 5/10):2 1/6*6]=[(5 10/90-1 45/90):2 1/6*6]=

=[(4 100/90-1 45/90):2 1/6*6]=[3 55/90:2 1/6*6]=

=[325/90:13/6*6]=[325/90*6/13*6]=150/15=10

f)

=1,1-0,36 / 1,32-(1+10*0,027)=

=0,74 / 1,32-(1+0,27)= 0,74 / 1,32-1,27=

=0,74 / 0,05=0,74:0,05=14,80
