[tex] \frac{1}{4} [/tex] of 357 is 89.25
Method 1: Multiplying as fractions
[tex] \frac{1}{4} [/tex] * [tex] \frac{357}{1} [/tex]
=[tex] \frac{1*357}{4*1} [/tex]
=[tex] \frac{357}{4} [/tex]
=89 [tex] \frac{1}{4} [/tex]
Method 2: Multiplying as decimals
[tex] \frac{1}{4} [/tex] is equal to 0.25
0.25*357=89.25
