a ) 3,6 + 2/3 = 3 6/10 + 2/3 = 3 18/30 + 20/30 = 3 38/30 = 4 8/30 = 4 4/15
b ) 4 1/8 - 1,11 = 4,125 - 1,11 = 3,015
c ) 2,75 + 2/7 = 2 3/4 + 2/7 = 2 21/28 + 8/28 = 2 29/28 = 3 1/28
d ) 0,125 - 1/9 = 1/8 - 1/9 = 9/72 - 8/72 = 1/72
e ) 3 1/3 - 3,3 = 3 1/3 - 3 3/10 = 3 10/30 - 3 9/30 = 1/30
f ) 1 1/5 - 0 , 09 = 1 1/5 - 9/100 = 1 20/100 - 9/100 = 1 11/100= 1,11
zad 16
a) 1- ( 2/5 + 2/25 ) = 1-10/25+2/25=1-12/25 = 13/25
b) 1-( 0,59 + 1/5 + 3/50) = 1-(0,59+0,2+0,06) = 1-0,85=0,15
mam nadzieję że pomogłam
