Lisa mixed a 1/2 (or .5) part of apple juice with each part of vanilla yogurt.

Answer:
6.6×10²¹
Step-by-step explanation:
6,600,000,000,000,000,000,000 → there are 21 place values after the first non-zero number ''6''
to convert to standard form, we move the decimal point after the first non-zero number.
<em>6,600,000,000,000,000,000,000</em><em>.</em><em>0 ← decimal in the end</em>
<em>the decimal </em>will be moved, all the digits after the decimal are counted and they will resemble the index.
6.6×10²¹
