1.23÷10 = 0.123 is a true statement

Given the expression 1.23÷10, we need to<u> check if the expression is equal to 0.123</u>

<h3>Fractions</h3>

Fractions is a ratio of two integers a/b

Given

  • 1.23÷10

Convert the decimal to a fraction as shown:

  • 1.23 = 123/100

The expression becomes:

  • 123/100 ÷10

= 123/100 * 1/10

=  123/1000

Convert back to decimal

1.23÷10 = 0.123

This shows that 1.23÷10 = 0.123 is a true statement
