Explanation:
So, when we divide one number by another, we are trying to figure out how many times the second number goes into the first number. In this case, we want to know how many times 8.5 goes into 123.25.
One way to do this is to use long division. Here are the steps:
1. Write the number 123.25 under the division symbol, and the number 8.5 outside the division symbol.
2. Ask yourself, "How many times does 8.5 go into 12?" The answer is 1, so write a 1 above the division symbol, above the 2 in 12.
Multiply 8.5 by 1 to get 8.5, and write that number under the 12.
Subtract 8.5 from 12 to get 3.5, and write that number next to the 5 in 123.25.
Bring down the next digit of the dividend (which is the 2 in 123.25) to the right of the 3.5 to get 35.
Ask yourself, "How many times does 8.5 go into 35?" The answer is 4, so write a 4 next to the 1 above the division symbol.
Multiply 8.5 by 4 to get 34, and write that number under the 35.
Subtract 34 from 35 to get 1, and write that number next to the 2 in 123.25.
Bring down the next digit of the dividend (which is the decimal point) to the right of the 1.
Add a decimal point to the answer above the division symbol, and bring it down next to the decimal point in the dividend.
Ask yourself, "How many times does 8.5 go into 10?" The answer is 1, so write a 1 next to the 4 above the division symbol.
Multiply 8.5 by 1 to get 8.5, and write that number under the 10.
Subtract 8.5 from 10 to get 1.5, and write that number next to the decimal point in the quotient.
Bring down the next digit of the dividend (which is the 5 in 123.25) to the right of the 1.5 to get 15.
Ask yourself, "How many times does 8.5 go into 15?" The answer is 1, so write a 1 next to the 5 in the quotient.
Multiply 8.5 by 1 to get 8.5, and write that number under the 15.
Subtract 8.5 from 15 to get 6.5.
So the final answer is 14.5, with a remainder of 6.5.
**We can write this as 14 with a remainder of 6.5/8.5, or as a mixed number 14 and 6.5/8.5.
I hope this explanation helps you understand how to divide 123.25 by 8.5!
