Question

Estimate the quotient $88÷13$ to its nearest tens.

• A. $9$
• B. $6$
• C. $10$
• D. $7$

Answer 1

Answer: (A)

$9$

$\Rightarrow$ In number $88$, its unit digit is $8$, which is greater than $5$.

$\Rightarrow$ So, we replace ones digits by $0$ and add $1$ to the other digits as they are to round off number nearest to 10. The number is $90$

$\Rightarrow$ In number $13$, its unit digit is $3$, which is less than $5$.

$\Rightarrow$ So, we replace ones digits by 0 and keep the other digits as they are to round off number nearest to 10. The number is $10$

$\therefore$ $88÷13=90÷10=9$
