e) 7/3+2-1/4=

f) -3/2+1/6+2-2/3=

Answer 1

Calcule:

a) -1-3/4 = -4-3 ==> - 7
                    4             4
==============================================
b) (-3/5)+ (1/2) = - 6+5 ==> -1/10
                                10
=============================================
c) 2-1/2-1/4= (8-2-1)/4 ==> 5/4
===================================================
d) -3-4/5+1/2= (-30-6+5)/10 ==> - 31/10
===================================================
e) 7/3+2-1/4=(28+24-3)/12 ==> 49/12
====================================================
f) -3/2+1/6+2-2/3= (-9+1+12-4)/6 ==> 0/6 ==> 0
