3. divide using partial quotients. then, check your work with multiplication!\na. 1,785 ÷ 7
Answer
Explanation:
Step1: Subtract 7*200 from dividend
$1785 - 7\times200 = 1785 - 1400 = 385$
Step2: Subtract 7*50 from remainder
$385 - 7\times50 = 385 - 350 = 35$
Step3: Subtract 7*5 from new remainder
$35 - 7\times5 = 35 - 35 = 0$
Step4: Sum partial quotients
$200 + 50 + 5 = 255$
Step5: Verify with multiplication
$255\times7 = 1785$
Answer:
The quotient is 255, and verification confirms $255\times7=1785$.
