Here’s and example of a **SMART MATH** problem for **ARITHMETIC.**

**Problem**

**Problem**

Find the smallest from: , , , and .

**The Usual Method**

[contentblock id=google-adsense-post]

Equate denominators by finding LCM.

LCM = 7 x 25 x 4 x 23 = 16100

Now correspondingly multiply numerators with the same multiple that is used to get the denominator = 16100.

As can be seen the smallest is =

**(Ans: 2)**

*Estimated Time to arrive at the answer = 150 seconds.*

**Using Technique**

Between and , is the smaller one. This eliminates option ‘4’.

Also, =

Similarly, =

Since, 0.35 < 0.43, eliminate option ‘1’.

Similarly, =

Since, 0.35 < 0.52, eliminate option ‘3’.

Similarly, =

Since, 0.35 < 0.65, eliminate option ‘5’.

Hence answer will be the left out option ‘2’.

(Note: In this case we are trying to bring the denominators close to 100 to get the decimal value of the fraction, so that it can directly be compared)

**(Ans: 2)**

*Estimated Time to arrive at the answer = 30 seconds.*
