Question

Two numbers, when rounded off to the nearest 100, are $a = 1500$ and $b = 2800$. Given that $a$ and $b$ are integers, find the largest value of $a - b$, the smallest value of $a + b$, the smallest value of $a \times b$, the largest value of $a \times b$, the smallest value of $\frac{a}{b}$, the largest value of $\frac{a}{b}$.

Accepted Answer

(a) $-1201$ (b) $4200$ (c) $3\,987\,500$ (d) $4\,413\,101$ (e) $\dfrac{1450}{2849}$ (f) $\dfrac{1549}{2750}$
