Question

0< a < c < 6 < g < k
What is the least possible value of a + k?
These integer problems always get me . I have no idea how to approach it . Please explain

Answer 1

We want the smallest a and k we can find

0<a and a is an integer, the smallest a=1;
since 6<g and g is an integer, the smallest g is g=7;
since g=7<k and k is an integer, the smallest k=8
thus the least a+k=1+8=9
