21/8= 2.625 = 2

Now the we have our whole number because that the blended fraction, we need to discover our brand-new numerator because that the fraction part that the blended number.

Step 2: obtain the new numerator

To occupational this out we"ll usage the entirety number we calculated in action one (2) and multiply the by the initial denominator (8). The an outcome of that multiplication is then subtracted indigenous the initial numerator:
