Of every 4 litre of Petrolyn Motor Oil, 3 litres is natural oil, or \(\frac{3}{4}\) of the oil is natural. That means that \(\frac{1}{4}\) of the oil is synthetic.
\(\frac{1}{4}\) of 357 is 89.25
Method 1: Multiplying as fractions
\(\frac{1}{4}\) \(\frac{357}{1}\)
=\(\frac{1*357}{4*1}\)
=\(\frac{357}{4}\)
=89 \(\frac{1}{4}\)
Method 2: Multiplying as decimals
\(\frac{1}{4}\) is equal to 0.25
0.25357=89.25
