Using approximations to 1 significant figure check that your answer to part a makes sense

Using the principle of approximation, the result of the questions posed are :

1.)

(13822 × 623) / 14

Using a calculator :

2.)

Using approximation :

13822 = 10000 (1 significant figure)

623 = 600 ( 1 significant figure)

14 = 10 (1 615079

significant figure)

Hence ;

(10000 × 600) / 10

6000000 / 10 = 600,000

Hence, the answer to part B is 600,000

A significant figure is the first digit in a number that isn't zero. You round to this.

Step-by-step explanation:

E.g. 1959302 to 1 Sig Fig = 2000000

You round to the first figure that isn't zero, which is one

E.g 0.000001373 to 1 Sig Fig = 0.000001 because that 1 is the first digit that isn't zero

the answer is c. 23/3
