Answer

Brief Explanations:

1.45 is rounded to 1.5 and 2.38 is rounded to 2.4. This is rounding each number to the nearest tenth. Front - end would focus on the left - most digits only, clustering is for numbers close to each other, and rounding to the nearest hundredth is not what's done here.

Answer:

C. rounding to the nearest tenth
