Divide to 100 with Regrouping: Number Bonds & Equations 3-112
Use number bonds and mental math to solve division regrouping problems fluently. What's 54÷3? 54 = 50+4, but neither 50 nor 4 are multiples of 3. Regroup by shifting 10 twice – shifting 20 in all – to make 30 and 24. Since 30÷3 = 10, 24÷3 = 8, and 10+8 = 18, 54÷3 = 18. Find and add partial quotients to get the total quotient.
