Instead of multiplying directly:
153.86 × 1.8 is tackled by rewriting 1.8 as (1 + 0.8):
153.86 × (1 + 0.8) -
Breaking it down into simpler terms:
Use the distributive property of multiplication:
= (153.86 × 1) + (153.86 × 0.8)
= 153.86 + (153.86 × 0.8) -
Compute 153.86 × 0.8:
0.8 is 8 × 0.1, so:
153.86 × 0.8 = 153.86 × (8 × 0.1) = (153.86 × 8) × 0.1
153.86 × 8 = 1230.88
Then × 0.1 → 123.088 -
Final addition:
153.86 + 123.088 = 276.948
This process avoids cumbersome repeated multiplication, reduces error, and makes intermediate steps transparent—critical for teaching and learning.
