Answer:
The proportion is true.
Step-by-step explanation:
By using the formula below, you can test the correctness of any proportion.
[tex]\frac{a}{b}=\frac{c}{d}[/tex]
[tex]ad=bc[/tex]
By plugging in the given numbers, you can test the proportion.
[tex]\frac{1.3}{4} =\frac{0.975}{3}[/tex]
[tex]1.3(3)=4(0.975)[/tex]
[tex]3.9=3.9[/tex]
Thus, the proportion is correct.
