Answer :
Let's solve the problem step by step.
The question is asking for the result of multiplying 93 decenas by 10.
1. Understand what a decena is: A "decena" is a Spanish term for a group of ten units. So, when you have 93 decenas, you have 93 groups of ten.
2. Convert decenas to a numerical value: Each decena is equal to 10 units. Therefore, 93 decenas is equal to 93 times 10 units. This is because each decena contains 10 units.
3. Perform the multiplication: Multiply 93 by 10 to find the total number of units:
[tex]\[
93 \times 10 = 930
\][/tex]
4. Determine the type of group: The result, 930, needs to be categorized into unidades (units), centenas (hundreds), or millares (thousands).
- Unidades (units) would mean each 1 represents a single unit, so 930 is just 930 units.
- Centenas (hundreds) means that 1 represents 100 units. To express 930 as centenas, divide it by 100:
[tex]\[
930 \div 100 = 9.3
\][/tex]
Since 9.3 is not a whole number of hundreds, 930 is not 93 centenas.
- Millares (thousands) means that 1 represents 1000 units. To express 930 as millares, divide it by 1000:
[tex]\[
930 \div 1000 = 0.93
\][/tex]
Since 0.93 is not a whole number of thousands, 930 is not 93 millares.
5. Choose the correct answer: From the given choices, we see that 930 corresponds best to 93 decenas. Since none of the choices directly corresponds to 930 without changing the type of group (hundreds or thousands), and considering our calculation, the correct answer is that 930 represents 93 centenas.
So, the correct answer is:
(C) 93 centenas
