Question

The product of which pair of numbers given below is a natural number ?

• A. $$\sqrt{5\frac{1}{2}},\sqrt{4\frac{1}{4}}$$
• B. $$\sqrt{7\frac{1}{2}},\sqrt{3\frac{1}{3}}$$
• C. $$\sqrt{\frac{1}{2}},\sqrt{2\frac{1}{2}}$$
• D. $$\sqrt{5\frac{1}{3}},\sqrt{3\frac{1}{2}}$$

Answer 1

Answer:

$$\sqrt{7\frac{1}{2}},\sqrt{3\frac{1}{3}}$$

$5\frac{1}{2} \times 4 \frac{1}{4}$

$\frac{11}{2}\times\frac{17}{4}$

$=7\frac{1}{2}\times3\frac{1}{3}$

$=\frac{15}{2} \times \frac{10}{3}$

$=5 \times 5 = 25$
