Question

express the following decimals in rational form first one 4.23 bar second one 0.54 bar​

Answer 1

Answer:

Rational numbers are numbers that can be expressed in the form of a fraction, i.e., p/q.

p refers to the numerator, while q was a non-0 denominator.

Since the value of q was always higher than 1, each integer could be called the rational number.

In the above question;

The rational form of 4.23 bar is 68/15

The rational form of 0.54 bar is 49/90

The 2 numbers are expressed in their rational forms in the following manner.

Answer 2

Step-by-step explanation:

Given Express the following decimals in rational form first one 4.23 bar second one 0.54 bar

• We need to express in p/q form.
• So x = 4.23 bar = 4.233333
• Multiply by 10 we get
• 10 x = 42.3333
• But x = 4.23333
• So subtracting we get
• 10x – x = 42.3333 – 4.23333
• 9x = 38.1
• So x = 38.1 / 9
• Or x = 381 / 90
• So x = 127 / 30
• Now also we have 0.54 bar  
• Let x = 0.544444
• Multiply both sides by 10 we get
• 10 x = 5.44444444
• Subtracting we get
• 10x – x = 5.444444 – 0.544444
• 9x = 4.9
• So x = 4.9 / 9
• Or x = 49 / 90
• Now they are in p/q or rational form
