Answer:

[tex]1:2 > 3:8[/tex]

Step-by-step explanation:

Given

[tex]Ratio_1 = 3:8[/tex]

[tex]Ratio_2 = 1:2[/tex]

Required

Compare both ratios

[tex]Ratio_1 = 3:8[/tex]

[tex]Ratio_2 = 1:2[/tex]

Multiply ratio 2 by 4

[tex]Ratio_1 = 3:8[/tex]

[tex]Ratio_2 = 1 * 4:2 * 4[/tex]

This gives:

[tex]Ratio_1 = 3:8[/tex]

[tex]Ratio_2 = 4:8[/tex]

Write both ratios as fractions

[tex]Ratio_1 = \frac{3}{8}[/tex]

[tex]Ratio_2 = \frac{4}{8}[/tex]

Get decimal equivalent:

[tex]Ratio_1 = 0.375[/tex]

[tex]Ratio_2 = 0.5[/tex]

Comparing both, we have that

[tex]Ratio_2 > Ratio_1[/tex]

[tex]0.5 > 0.375[/tex]

Conclusively;

[tex]1:2 > 3:8[/tex]

Answer:

3:8 < 1:2
