Question

1. number sense maya has 462 pennies. use mental math to find how many pennies are left if she puts them in stacks of 50 pennies. explain your reasoning.

Explanation:

Step1: Find how many 50s in 462

We know that \( 50\times9 = 450 \) (since \( 50\times10 = 500 \) which is more than 462, so we take 9 stacks of 50).

Step2: Calculate the remainder

To find the number of pennies left, we subtract the total number of pennies in the stacks from the total number of pennies Maya has. So, \( 462 - 450 = 12 \).

Answer:

12
