Explanation
Plug in your own numbers for c and h.
Let’s say Elier can bake 14 cakes in 2 hours; this makes c = 14 and h = 2. That means he can bake 7 cakes per hour. At this rate, it will take him 111 hours to bake 777 cakes. Circle 111 as your target number. When you plug in your values, choices (A) and (D) are way too big. Choices (C) and (E) are way too small. Using your calculator, you can determine that choice (B) matches.

Elier can bake c cakes in h hours
So, Elier can bake ONE cake in h/c hours
So, Elier can bake TWO cakes in 2h/c hours (twice the time for ONE cake)
So, Elier can bake THREE cakes in 3h/c hours (three times the time for ONE cake)
.
.
.
So, Elier can bake 777 cakes in 777h/c hours
