Select one of the four options:

A. [tex]$158 \frac{45}{100}$[/tex]
B. [tex]$157 \frac{44}{100}$[/tex]
C. [tex]$157 \frac{43}{100}$[/tex]
D. [tex]$156 \frac{42}{100}$[/tex]

Answer :

We start with the decimal number:

[tex]$$157.43$$[/tex]

Step 1: Identify the integer part.

The integer part here is [tex]$$157.$$[/tex]

Step 2: Identify the fractional part.

The fractional part is [tex]$$0.43.$$[/tex] This can be written as a fraction by noting that:

[tex]$$0.43 = \frac{43}{100}.$$[/tex]

Step 3: Simplify the fraction.

We now reduce the fraction [tex]$$\frac{43}{100}$$[/tex] to its lowest terms. To do this, we find the greatest common divisor (gcd) of the numerator and denominator. We check:

[tex]$$\gcd(43, 100) = 1.$$[/tex]

Since the gcd is [tex]$$1,$$[/tex] the fraction is already in simplest form.

Step 4: Write the mixed number.

The mixed number is obtained by combining the integer part and the simplified fraction:

[tex]$$157\frac{43}{100}.$$[/tex]

Thus, the final answer is:

[tex]$$\boxed{157\frac{43}{100}}.$$[/tex]
