Question

For x=2/5 and y=-7/11,is |x+y| =|x| +|y| ? If not , find the rational numbers between |x+y| and |x| + |y|
step by step
​

Answer 1

|2/5-7/11|=|0.4-0.63|=|-0.23|=0.23

|2/5|+|-7/11|=2/5+7/11=1.03

so

|x+y|not equal to |x|+|y|

rational numbers between 0.4 and 0.63636363...are

0.41

0.42

0.43
