15.4 subtract 8.88 equals what?

We could round 8.88 to its nearest whole number, which is nine. To round 8.88 to nine, we had to add 0.12. This means we’re taking away 0.12 too much. So we’ll need to add this back on to the answer. 15.4 subtract nine is 6.4. And 6.4 plus 0.12 equals 6.52.

We started at 15.4. We subtracted nine then added 0.12 to give us our answer of 6.52. 15.4 subtract 8.88 equals 6.52.
