Question

(5×3)×20 (7×2)×50 (50×5)×2 60×(3×5)

Answer 1

1)(5*3)*20=300
2)60*(3*5)=900
3)(7*2)*50=720
4)(50*5)*2=500

Answer 2

Let's solve each of these expressions step by step:

1. (5×3)×20 = 15×20 = 300

2. (7×2)×50 = 14×50 = 700

3. (50×5)×2 = 250×2 = 500

4. 60×(3×5) = 60×15 = 900

So the final results are:

1. (5×3)×20 = 300
2. (7×2)×50 = 700
3. (50×5)×2 = 500
4. 60×(3×5) = 900
