[tex]\frac{4}{10} \text { and } \frac{10}{25}[/tex]
Step-by-step explanation:
(A) [tex]\frac{4}{9} \text { and } \frac{9}{4}[/tex]
When cross multiply the fractions, we get
⇒ 4 × 4 = 9 × 9
⇒ 16 ≠ 36
So, [tex]\frac{4}{9} \text { and } \frac{9}{4}[/tex] do not form a proportion.
(B) [tex]\frac{4}{11} \text { and } \frac{6}{13}[/tex]
When cross multiply the fractions, we get
⇒ 4 × 13 = 6 × 11
⇒ 52 ≠ 66
So, [tex]\frac{4}{11} \text { and } \frac{6}{13}[/tex] do not form a proportion.
(C) [tex]\frac{4}{10} \text { and } \frac{10}{25}[/tex]
When cross multiply the fractions, we get
⇒ 4 × 25 = 10 × 10
⇒ 100 = 100
So, [tex]\frac{4}{10} \text { and } \frac{10}{25}[/tex] form a proportion.
(D) [tex]\frac{3}{5} \text { and } \frac{9}{25}[/tex]
When cross multiply the fractions, we get
⇒ 3 × 25 = 9 × 5
⇒ 75 ≠ 45
So, [tex]\frac{3}{5} \text { and } \frac{9}{25}[/tex] do not form a proportion.
