c) (4, 45 - 2 1/2):0,6
prosze pomocy
a. 3⅜ + 7/4 - 3/5 = 27/8 + 7/4 -3/5 = 27/8 + 14/8 -3/5 = 41/8 -3/5= 205/8-24/8= 181/8
b. 1 2/9 - 2/3 = 11/9 - 6/9 = 5/9
c. 3/4 : 55/3 = 3/4 * 3/55= 12/220 = 3/55
d. (89/20 - 5/2):3/5= (89/20 - 50/20):3/5= 39/20*5/3= 195/60=39/12=13/4
a) 2 3/8 + 1,75 - 15/25= 2,375 + 1,75 - 60/100= 2,375 + 1,75 - 0,6= 3,525
b) 1 2/9 - 2/3= 1 2/9 - 6/9= 5/9
1 3/4 : 18 1/3= 7/4 : 55/3= 7/4 * 3/55= 21/165= 7/55
c) ( 4,45 - 2 1/2) : 0,6= ( 4,45 - 2,5) : 0,6= 1,95 : 0,6= 3,25
