Question

Answer 1

hi again

Answer 2

How far did you get with this one?

Answer 3

not really far at all im kinda stupid when it comes to math sooooooooo

Answer 4

so what I like to do when solving problems is to jump immediately to the question at hand

"what is the total number of dancers in the school?"

We don't know this value, so lets call it x
x = number of dancers at the school

Answer 5

ok

Answer 6

we are told that 42% of all the dancers are ballet dancers, and there are 63 ballet dancers

this means
42% of x = 63

Agreed?

Answer 7

agreed

Answer 8

change the 42% into 0.42
this is because 42% = 42/100 = 0.42

Also change the "of" into a multiplication symbol

We go from
42% of x = 63
to
0.42*x = 63

Answer 9

how can we solve for x in 0.42*x = 63 ?

we need to undo that multiplication somehow

what is the opposite of multiplication?

Answer 13

um division

Answer 14

yes, so we'll divide both sides by 0.42

Answer 15

On the left side, when you divide by 0.42, the "0.42" terms go away
On the right side, what is 63/0.42 equal to?

Answer 16

umm its equal to i don't know anything about mathhhhhhhhh

Answer 17

Answer 18

ok hold on what am using a calcultor for

Answer 19
