Let's convert each of the fractions you provided into decimal form:
-
1.5 over 8:
\( 1.5 \div 8 = 0.1875 \) -
2.1 3 over 4:
First, convert \( 2.1 \) into an improper fraction by recognizing \( 2.1 = \frac{21}{10} \) and \( 3/4 = \frac{3}{4} \). Adding these gives:
\(\frac{21}{10} + \frac{3}{4}\)
To add, find a common denominator (which is 20):
\( \frac{21 \times 2}{10 \times 2} + \frac{3 \times 5}{4 \times 5} = \frac{42}{20} + \frac{15}{20} = \frac{57}{20} \)
Now convert to decimal:
\( \frac{57}{20} = 2.85 \) -
5 over 7:
\( 5 \div 7 \approx 0.7142857 \) (continuing, it is approximately \( 0.7143 \) when rounded to four decimal places) -
7 over 25:
\( 7 \div 25 = 0.28 \) -
2 5 over 6:
Convert \( 2 \frac{5}{6} \) into an improper fraction:
\( 2 = \frac{12}{6} \) and thus, \( 2 \frac{5}{6} = \frac{12}{6} + \frac{5}{6} = \frac{17}{6} \)
Convert to decimal:
\( \frac{17}{6} \approx 2.8333 \) (approximately) -
17 over 8:
\( 17 \div 8 = 2.125 \)
To summarize, here are the decimal conversions:
- 1.5 over 8 = 0.1875
- 2.1 3 over 4 = 2.85
- 5 over 7 = 0.7143
- 7 over 25 = 0.28
- 2 5 over 6 = 2.8333
- 17 over 8 = 2.125
