Answer:
False. The products from cross multiplication are different.
Explanation:
To know if a pair of ratios form a proportion, cross multiply. If the products are equal, they are a proportion.
Write like this to see top (numerator) and bottom (denominator) clearly.
![(4)/(5) =(5)/(6)](https://img.qammunity.org/2021/formulas/mathematics/college/1uhze339k6a62o5ly3h4ccdlctgq65u3ny.png)
Multiply each numerator with the other side's denominator:
4 X 6 = 24
5 X 5 = 25
Are they equal? No. 24 ≠ 25
Therefore it's not a proportion.
