Question

complete the pattern:

□÷3 = 3

90÷□ = 30

900÷3 = □

□÷3 = 3,000

Explanation:

Step1: Solve the first blank

Let the number be $x$. Then $x\div3 = 3$. By the rule of division (dividend = divisor $\times$ quotient), $x=3\times3 = 9$.

Step2: Solve the second blank

Let the number be $y$. Then $90\div y = 30$. By the rule of division (divisor = dividend $\div$ quotient), $y = 90\div30=3$.

Step3: Solve the third blank

Calculate $900\div3$. Using long - division or mental math, $900\div3 = 300$.

Step4: Solve the fourth blank

Let the number be $z$. Then $z\div3 = 3000$. By the rule of division (dividend = divisor $\times$ quotient), $z = 3\times3000=9000$.

Answer:

9, 3, 300, 9000
