How do I write this problem in standard form 45 tens + 7 ones

Answer 1

Hello! You asked how to write "45 tens + 7 ones" in standard form.

First, let's start with the "45 tens." If you have 45 tens, this means you have 45 groups of 10. 45 groups of 10 is written mathematically as 45*10. 45*10=450.

Then, let's do "7 ones." 7 ones means that you have 7 groups of 1. We write this mathematically as 7*1, and we know that 7*1=7.

Finally, we add all of the pieces together. The question asks us fro "45 tens + 7 ones", and we found that 45 tens = 450, and 7 ones = 7. So, we replace 45 tens with 450, and 7 ones with 7. 450+7=457, which is our answer.
