Which of the following represents the relative frequency table and the percent bar graph summarizing the survey results?

Answer:

62 + 9 = 71.

Step-by-step explanation:

Break Apart to make tens is a strategy to help children to add numbers in a easier way. This is applied when they have to sum 2-digits number, which is new for them.

So, first we could think about how many units in 62 are left to each 70, we'll find that 8 units are left to reach 70. So, this 8 will help to break the simplest part, which is 9, we can rewrite 9 as the sum of 8+1.

Then, the next step is add 62+8, because kids know that makes a ten, 62+8=70, now we have a ten formed. Lastly, we just add the second number missing, which is 1. 70+1=71.

You see, this strategy consist in making tens to help children to sum, because they are familiarize with sum based on tens.

Final answer:

To add 62 and 9, break apart the 9 into 1 and 8. Add the ones and tens place separately, then combine them to get the final sum of 73.

Explanation:

To add 62 and 9, start by breaking apart the 9 into a 1 and an 8. Now, you can add the ones place of 62 with the one from 9, which gives you a sum of 3. Then, add the tens place of 62 with the eight, which gives you a sum of 70. Therefore, 62 + 9 = 70 + 3 = 73.
