Need the full answe with every step and show you're work please
To determine how much fabric Katrina should buy, we need to consider that the fabric is sold in lengths of whole meters and tenths of meters.
Given that Katrina needs 1.56m of fabric, we have two options for purchasing the fabric: buying 1.5m or 1.6m.
To decide between these options, we can round up or down based on the following rule: if the decimal part is 0.1 or greater, we round up to the nearest whole meter; otherwise, we round down.
In this case, the decimal part is 0.56, which is greater than 0.1. Consequently, we should round up to the nearest whole meter when buying fabric.
Therefore, Katrina should buy 1.6m of fabric to ensure she has enough to make her curtains.
