Answer:
Best for choice for the first number to subtract = 500
Step-by-step explanation:
The dividend is 673 while the divisor is 25
First step is to subtract from the dividend an easy multiple like 100 times the divisor,20 times the divisor, 10 times the divisor, 5 times the divisor 2 times the divisor etc.
The best choice for the first number to subtract will be 20 times the divisor because when we multiply 20 by 25 and subtract from 673,we will get 173. And the next quotient will be 6 which is in units as the first one of 20 was in tens.
Best choice to subtract = 20 × 25 = 500
