Fot 2 decimal places you can easily use the approximation for pi=22/7. So circumference = pi x diameter = 14 x 22/7 = 44
0.62 = 31/50
Stated to 2 decimal places, it's 342.99Rounded to 2 decimal places, it's 343.00
It is 4.97 rounded to 2 decimal places

It is 3/4 that is equivalent to the decimal of 0.75
1.76 to 2 decimal places = 1.76
Stated to 2 decimal places, it's 342.99Rounded to 2 decimal places, it's 343.00
The simplest, one-step, way is to multiply by 1.3. But if your arithmetical skills are not up to that the longer way is: Step 1: divide the number by 10 (move the decial point one place to the left) Step 2: multiply the result by 3 Step 3: add this to the original number. Or Step 1: divide the number by 10 (move the decial point one place to the left) Step 2a: add this to the original number (+ 10%) Step 2b: add again (+ 20%) Step 2c: add yet again (and you've got + 30%).
1.35 to 2 decimal places is 1.35 (1.35 is already to 2 decimal places.)
