Answer :
To determine whether the proportion [tex]\(\frac{48}{20} = \frac{60}{25}\)[/tex] is true or false, we need to simplify both ratios and compare them.
1. Simplifying [tex]\(\frac{48}{20}\)[/tex]:
- Find the greatest common divisor (GCD) of 48 and 20. The GCD is 4.
- Divide the numerator and the denominator by 4:
[tex]\[
\frac{48}{20} = \frac{48 \div 4}{20 \div 4} = \frac{12}{5}
\][/tex]
2. Simplifying [tex]\(\frac{60}{25}\)[/tex]:
- Find the greatest common divisor (GCD) of 60 and 25. The GCD is 5.
- Divide the numerator and the denominator by 5:
[tex]\[
\frac{60}{25} = \frac{60 \div 5}{25 \div 5} = \frac{12}{5}
\][/tex]
3. Compare the simplified ratios:
- Both simplified ratios are [tex]\(\frac{12}{5}\)[/tex].
Since both ratios simplify to [tex]\(\frac{12}{5}\)[/tex], the original proportion [tex]\(\frac{48}{20} = \frac{60}{25}\)[/tex] is true.
