Your Turn: Using the figure, a

Hatshy [7]

We are given:
$\frac{a}{c} = \frac{d}{a}$

First step is to get rid of fractions. We start by multiplying both sides by a.
$\frac{a}{c} = \frac{d}{a} /*a \\$

Now we cancel a on right side and we multiply both sides by c.
$\frac{ a^{2}}{c} = \frac{da}{a} /*c \\ \frac{ a^{2}c}{c} = dc$

After canceling c on the right side we are left with:
$a^{2} = dc or a^{2} = cd$

Find the smallest number should be subtracted from 9340 so as to get a perfect square.

nikdorinn [45]

Square root of 9340 = 96.64

nearby number = 96

square of 96 = 9216

9340- 9216= 124

the smallest number 124 should be subtracted from 9340 so as to get a perfect square.
