A team allocates 168 minutes to planning, building, and checking in the ratio 3:4:5. Which allocation is correct?

Explicación

The 12 ratio parts are worth 14 minutes each, so the ordered shares are 42, 56, and 70 minutes. The near allocation 42, 60, and 66 totals correctly but does not keep the three quantities in a 3:4:5 ratio.
