Keenan got [tex]\frac{13}{25}[/tex] for his Mathematics test.

1. Write down two equivalent fractions for this mark.

2. Write this fraction as a decimal.

If the pass percentage for a Mathematics class test is [tex]40\%[/tex], did Keenan pass this test and what was his percentage?



Answer :

Certainly! Let's go through each part of the problem step-by-step.

### Part 1: Equivalent Fractions

To find equivalent fractions, you can multiply the numerator and denominator by the same number. Here are two examples:

1. First Equivalent Fraction:
Multiply both the numerator (13) and the denominator (25) by 2:
[tex]\[ \frac{13 \times 2}{25 \times 2} = \frac{26}{50} \][/tex]

2. Second Equivalent Fraction:
Multiply both the numerator (13) and the denominator (25) by 4:
[tex]\[ \frac{13 \times 4}{25 \times 4} = \frac{52}{100} \][/tex]

So, the two equivalent fractions are [tex]\(\frac{26}{50}\)[/tex] and [tex]\(\frac{52}{100}\)[/tex].

### Part 2: Decimal Fraction

To convert the fraction [tex]\(\frac{13}{25}\)[/tex] to a decimal, you simply divide the numerator by the denominator:
[tex]\[ \frac{13}{25} = 0.52 \][/tex]

So, the decimal fraction for [tex]\(\frac{13}{25}\)[/tex] is [tex]\(0.52\)[/tex].

### Part 3: Percentage and Pass Status

To convert a fraction to a percentage, multiply the decimal form by 100:
[tex]\[ 0.52 \times 100 = 52\% \][/tex]

So, Keenan's percentage mark is [tex]\(52\%\)[/tex].

The passing percentage for the test is [tex]\(40\%\)[/tex]. Since [tex]\(52\%\)[/tex] is greater than [tex]\(40\%\)[/tex], Keenan did pass the test.

### Summary

- Two equivalent fractions for [tex]\(\frac{13}{25}\)[/tex] are [tex]\(\frac{26}{50}\)[/tex] and [tex]\(\frac{52}{100}\)[/tex].
- The decimal fraction of [tex]\(\frac{13}{25}\)[/tex] is [tex]\(0.52\)[/tex].
- Keenan's percentage is [tex]\(52\%\)[/tex], which means he passed the test as this is above the pass mark of [tex]\(40\%\)[/tex].
