Answer 1

A)4 5/9+2 1/3 *4 1/2 = 4 5/9 + 7/3*9/2=4 10/18 + 10 9/18=15 1/18

b)5 1/7 *1 4/9 -6 :4 2/3= 36/7*13/9-6/1*3/14=52/7-9/7=43/7=6 1/7

c)3 1/2 * (2 1/4 -1 1/2 :6) = 7/2 * (2 1/4 - 3/2*1/6) = 7/2*(1 5/4 - 1/4) = 7/2*8/4=28/4=7

d) 5 2/9-1 1/6              5 4/18 - 1 3/18        73/18

-----------------------  =   -------------------- =  ---------- =  73/18 * 4/11 = 146/99=1 47/99

3 2/3 *(1 1/4-1/2)        11/3 * 3/4                11/4
