Write an expression that illustrates the intermediate steps required to mentally perform the specified computation using adjustment.
.
A.
B.
C.
D.

To mentally compute using an adjustment strategy, you can round to a number that’s easier to divide. For example, rounding it up to makes the division simpler. So you might visualize it as:

.

This means you’re adjusting from a round number back down, making the calculation straightforward!

Furthermore, option C not only simplifies your process but also helps you keep track of your adjustments, allowing you to subtract the 40 after performing the division on a simpler number. It’s a great way to manage mental math without getting overwhelmed!
