Janice is dividing 1.92 divided by 6. why does she exchange the place value blocks shown for 18 tenths and 12 ones ? ​

9 Godinez me. 333 12

To compute 1.92 divided by 6 you can multiply 1.92 by 100, compute the division and finally, divide the result by 100. So, 1.92*100 = 192, which can be represented as 18 tenths and 12 ones. This representation is convenient because both 18 and 12 are multiples of 6. Then, dividing 18 tenths by 6 we get 3 tenths (30), and dividing 12 ones by 6 we get 2 ones (2). The addition of the results of these partial divisions is 30 + 2 = 32, which is the result of 192/6. To get 1.92/6 we need to divide 32 by 100, which is 0.32, and that's the result of 1.92/6.
