Convert the following mixed number to improper fraction10 /2/57 3/20

Sagot :

The question asks us to convert mixed fractions to improper fraction.

The first Mixed fraction is:

[tex]\begin{gathered} 10\frac{2}{5} \\ \text{whole number = 10} \\ \text{ numerator = 2} \\ \text{ denominator = 5} \end{gathered}[/tex]

In order to convert this into an improper fraction, we need to follow some steps:

1. Multiply the denominator by the whole number.

2. Add the result of the multiplication in step 1 to the numerator.

3. The result from step 2 is the new numerator and use the current denominator as the new denominator.

Let us now apply these steps to answer the question

1. Multiply the denominator by the whole number.

[tex]5\times10=50[/tex]

2. Add the result of the multiplication in step 1 to the numerator.

[tex]50+2=52[/tex]

3. The result from step 2 is the new numerator and use the current denominator as the new denominator.

[tex]\begin{gathered} \text{new numerator = 52} \\ \text{new denominator = 5} \\ \therefore\frac{52}{5} \end{gathered}[/tex]

Therefore, the answer is:

[tex]10\frac{2}{5}=\frac{52}{5}[/tex]

Now, let us use the same rules for the next question.

[tex]7\frac{3}{20}[/tex]

1. Multiply the denominator by the whole number.

[tex]7\times20=140[/tex]

2. Add the result of the multiplication in step 1 to the numerator.

[tex]140+3=143[/tex]

3. The result from step 2 is the new numerator and use the current denominator as the new denominator.

[tex]\begin{gathered} \text{new numerator= 143} \\ \text{new denominator = 20} \\ \therefore\frac{143}{20} \end{gathered}[/tex]

Therefore, the final answer is:

[tex]7\frac{3}{20}=\frac{143}{20}[/tex]
