Step 1: Convert the mixed numbers into improper fractions

358=3×8+58

=298

 

225=2×5+25

=125

 

358×225 now becomes  298×125

Step 2: Cross Simplify [If Applicable] and multiply
When we look at the fractions to cross-simplify, we find that 12 and 8 have a common factor of 4. We can now reduce the fraction by 4. 

298×125=29×(12÷4)(8÷4)×5

=29×32×5

=8710

Step 3: Simplify [If Possible] and convert into a mixed number
Convert the improper fraction into a mixed number.

8710=87÷10
