Question

lets divide the whole and the divisor each by 10. whats our new expression? 6.36÷73≈6.3÷70 = □÷7

Explanation:

Step1: Analyze the transformation

We know that when we divide both the dividend and the divisor of a division - expression by the same non - zero number, the quotient remains the same. In the expression $6.3\div70$, if we divide the divisor 70 by 10 to get 7, we also need to divide the dividend 6.3 by 10.

Step2: Calculate the new dividend

$6.3\div10 = 0.63$. So the new expression is $0.63\div7$.

Answer:

$0.63$
