7. QUESTION
3 5/8 × 2 2/5 =
Step 1: Convert the mixed numbers into improper fractions
3 5/8 = (3×8+5)/8
= 29/8
2 2/5 = (2×5+2)/5
= 12/5
3 5/8 × 2 2/5 now becomes 29/8 × 12/5
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.
29/8× 12/5= 29×(12÷4)/(8÷4)×5
= 29×3/2×5
= 87/10
Step 3: Simplify [If Possible] and convert into a mixed number
Convert the improper fraction into a mixed number.
87/10 = 87 ÷ 10
= 8 7/10
