which of the following its true?

a)6/16=4/14
b)30/40=24/36
c)10/15=45/50
d)16/28=12/21

1 answer

To determine which of the statements is true, we can simplify each fraction and compare them.

a) \( \frac{6}{16} = \frac{4}{14} \)

  • Simplifying \( \frac{6}{16} \) gives \( \frac{3}{8} \).
  • Simplifying \( \frac{4}{14} \) gives \( \frac{2}{7} \).
  • \( \frac{3}{8} \neq \frac{2}{7} \)

b) \( \frac{30}{40} = \frac{24}{36} \)

  • Simplifying \( \frac{30}{40} \) gives \( \frac{3}{4} \).
  • Simplifying \( \frac{24}{36} \) gives \( \frac{2}{3} \).
  • \( \frac{3}{4} \neq \frac{2}{3} \)

c) \( \frac{10}{15} = \frac{45}{50} \)

  • Simplifying \( \frac{10}{15} \) gives \( \frac{2}{3} \).
  • Simplifying \( \frac{45}{50} \) gives \( \frac{9}{10} \).
  • \( \frac{2}{3} \neq \frac{9}{10} \)

d) \( \frac{16}{28} = \frac{12}{21} \)

  • Simplifying \( \frac{16}{28} \) gives \( \frac{4}{7} \).
  • Simplifying \( \frac{12}{21} \) gives \( \frac{4}{7} \).
  • \( \frac{4}{7} = \frac{4}{7} \)

Therefore, the true statement is:

d) \( \frac{16}{28} = \frac{12}{21} \)
