Question
Jacob likes playing math games with his father. His father wrote a mystery number and said, I will get 3.3 when I divide the mystery number by 3.How many tenths are there in this mystery number?
Solution
Step 1: Understand the problem. Jacob's father has a mystery number that when divided by 3 gives 3.3.
Step 2: To find the mystery number, we need to do the opposite of division, which is multiplication. So, we multiply 3.3 by 3.
Step 3: 3.3 * 3 = 9.9. So, the mystery number is 9.9.
Step 4: To find out how many tenths are in this number, we need to understand that the first digit after the decimal point represents tenths.
Step 5: In the number 9.9, there are 9 tenths.
