Let's follow the steps to help Marco find how many dekagrams are in 77 centigrams.
1. Circle the given unit: In this case, the given unit is centigrams. So, we circle "centi-" in the table.
2. Count the number of blocks to the desired unit: We want to convert from centigrams to dekagrams. Counting the blocks from "centi-" to "deka-" in the table:
- From centi- to unit (1 block)
- From unit to deka- (1 block)
So that's a total of 2 blocks.
3. Move the decimal point that many places in the same direction: Since we are moving from centigrams to dekagrams, which is to the left on our table, we move the decimal point in our given number 2 places to the left.
Starting with 77 centigrams:
- Moving the decimal point 2 places to the left gives us [tex]\(0.77\)[/tex].
Therefore, there are [tex]\(0.077\)[/tex] dekagrams in 77 centigrams.
