Question

Select the ratios that are equivalent to 11:1.Choose 3 answers:A-1:11B-22:2C-55:5D-9:99E-110:10

Answer 1

B)22:2, C)55:5 and E)110:10

Step-by-step explanation:

To select the equivalent ratios, educe each of the options to its lowest term where possible:

`\begin{gathered} A)1\colon11 \\ B)22\colon2=(22)/(2)\colon(2)/(2)=11\colon1 \\ C)55\colon5=(55)/(5)\colon(5)/(5)=11\colon1 \\ D)9\colon99=(9)/(9)\colon(99)/(9)=1\colon11 \\ E)110\colon10=(110)/(10)\colon(10)/(10)=11\colon1 \end{gathered}`

Options B, C, and E reduce to 11:1.

Thus, the equivalent ratios are (B)22:2, (C)55:5 and (E)110:10
