Question

estimate the difference by rounding each number to 0, $\frac{1}{2}$, or 1 before subtracting. $\frac{1}{3}-\frac{2}{7}$
a 0
b $\frac{1}{2}$
c 1

Explanation:

Step1: Round $\frac{1}{3}$ to nearest value

$\frac{1}{3} \approx 0$ (since $\frac{1}{3} \approx 0.33$, closer to 0 than $\frac{1}{2}$)

Step2: Round $\frac{2}{7}$ to nearest value

$\frac{2}{7} \approx 0$ (since $\frac{2}{7} \approx 0.29$, closer to 0 than $\frac{1}{2}$)

Step3: Subtract rounded values

$0 - 0 = 0$

Answer:

A. 0
