Shaniqua correctly finds the closest benchmarks for three numbers.

Three-sevenths is closest to the benchmark One-half
StartFraction 5 over 21 EndFraction is closest to the benchmark 0
0.87 is closest to the benchmark 1

Which shows the numbers Three-sevenths, StartFraction 5 over 21 EndFraction, and 0.87 in order from greatest to least?

StartFraction 5 over 21 EndFraction, 0.87, Three-sevenths
StartFraction 5 over 21 EndFraction, Three-sevenths, 0.87
0.87, StartFraction 5 over 21 EndFraction, Three-sevenths
0.87, Three-sevenths, StartFraction 5 over 21 EndFraction
