I need help with this. Can someone help me please. A wheel makes 6 7/15 revolutions per minute. If it rotates for 80 minutes, how many revolutions does it make?

    67/15 x 80 = 357.33 revolutions

    since per minute its making 6 full revolutions + 7/15th of a revolution, in 80 minutes it would make 80*6 + 80*7/15 revolutions

    i kind of got it but not really. Algebra is very complicated

    if we rush, it looks complicated. go slow, then it would make sense

    80*6=480+80=560*7/15 im comfuse with the 7/15

    ok, so u get how its ( 80*6 + 80*7/15 ) revolutions in 80 minutes, but u want to knw how to simplify it, right ?
