When are you going to use "much less than" when comparing?

Two examples:

I enjoyed that concert much less than I enjoyed last year's.

There is a large amount of sand in the little girl's sandbox, but it has much less than is in the big sandbox in the park.

The sandbox sentence is grammatically awkward, with ambiguous antecedents and confusion between the sand and the box.

IMHO.

The phrase "much less than" is commonly used when comparing two quantities or values to illustrate a significant difference between them. It indicates that the first quantity is considerably smaller or lower than the second quantity.

To use "much less than" when comparing, follow these steps:

1. Identify the two quantities or values you want to compare.
2. Determine the relative magnitudes of the two quantities.
3. If the first quantity is significantly smaller or lower than the second quantity, you can express this using the phrase "much less than."
4. When stating the comparison, you typically mention the first quantity followed by "is much less than" and then the second quantity.

For example, let's say you want to compare the population of two cities: City A and City B. If City A has a population of 10,000 and City B has a population of 100,000, you would say "The population of City A is much less than the population of City B."

By using the phrase "much less than," you emphasize the substantial difference in magnitude between the two quantities, highlighting that City A's population is significantly smaller than City B's population.
