Answer 1

hola :3

1-

$1/4+(3/5+2/5) = 1\frac{1}{4}$

$=1/4+1$

$=\frac{1}{4} +1$

$=\frac{5}{4}$

$=1\frac{1}{4}$

2-

$11/43+(-11/43)$

$=11/43+ \frac{-11}{43}$

$=\frac{11}{43}+\frac{-1}{43}$

$=0$

3-

$11/7+0/1$

$=\frac{11}{7} +0/1$

$=\frac{11}{7} +0$

$=\frac{11}{7}$

$=1\frac{4}{7}$

4-  

$(7/12+4/10)+3/6$

$= \frac{59}{60} +3/6$

$=\frac{59}{60} +\frac{3}{6}$

$=\frac{89}{60}$
