Answer:
1. 3/7
2. 28/135
Step-by-step explanation:
Ex: 1/2 × 3/5
• Multiply both numerators.
1 × 3 = 3
• Multiply both denominators.
2 × 5 = 10
Therefore the product of 1/2 × 3/5 is 3/10
1. 3/5 × 5/7
Numerator:
• 3 × 5 = 15
Denominator:
• 5 × 7 = 35
15/35 can be simplified.
15÷5/35÷5 = 3/7
2. 8/15 × 7/18
• 8 × 7 = 56
• 15 × 18 = 270
56/270 can be simplified.
56÷2/270÷2 = 28/135
