2.4 and1/8+1.235 = 33/8+1.235 = 4.125+1.235 = 5.36.

3:3 5/6-2.2 = 23/6+ 1 1/5 = 1 15/30+66/30 = 18 1/30

4: 1.25/3/4= 1.25*4/3=5/3

5:= 1.2*4/ 15*3/8= 1.6/5*3/8=0.6/5=0. 12

6:=7/ 15*3/ 14/2/5= 1/ 10*5/2= 1/4

Simple:

= 15/4* 1.6+5.5*5/22=6+ 1.25=7.25

=3/29* 100/ 15*7.25=20/29*7.25= 145/29=5

=0.4*5/2*9* 15/3= 1*45=45

=79/ 14*3/5+3/ 14=237/70+ 15/70=252/70=3.6

=4.5*(24/8)-2.5= 13.5-2.5= 1 1
