Question

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?

Answer 1

67/15 x 80 = 357.33 revolutions

Answer 2

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

Answer 3

How you multiply 7/15

Answer 4

Im still confuse with this problem.

Answer 5

which part u confuse wid ?

did u get how it makes ( 80*6 + 80*7/15 ) revolutions in 80 minutes ?

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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 ?

Answer 10

yes, your right. how too simplify it

Answer 11

80*6 + 80*7/15

480 + 560/15

Answer 12

we can simplify further.

Answer 13

How would you answer the problem.

Answer 14

80*6 + 80*7/15

480 + 560/15

480 + (555 + 5)/15

Answer 15

80*6 + 80*7/15

480 + 560/15

480 + (555 + 5)/15

480 + 555/15 + 5/15

Answer 16

fine, so far ?

Answer 17

i did nothing fancy, i just wrote 560 = 555 + 5

Answer 18

ok.

Answer 19

is the answer 560/15

Answer 20

15 goes in 555 , right ?

Answer 21

yes

Answer 22

80*6 + 80*7/15

480 + 560/15

480 + (555 + 5)/15

480 + 555/15 + 5/15

480 + 37 + 5/15

Answer 23

15 goes in 555, 37 times

Answer 24

80*6 + 80*7/15

480 + 560/15

480 + (555 + 5)/15

480 + 555/15 + 5/15

480 + 37 + 5/15

517 + 5/15

Answer 25

80*6 + 80*7/15

480 + 560/15

480 + (555 + 5)/15

480 + 555/15 + 5/15

480 + 37 + 5/15

517 + 5/15

517 + 1/3

517 1/3

Answer 26

we are done wid simplifying !

Answer 27

see if that makes sense :)

Answer 28

ok it does make since. I get it lol

Answer 29

glad to hear friend :)
