Respuesta :
180=3/7 you would do 180/3 which is 60 so 60=1/7 so to get the total you would do 60×7 which is 420 lol
Alright, lets get started.
Method 1:
Suppose Luann gets total monthly minutes = x
She spent [tex] \frac{3}{7} [/tex] of her monthly minutes means
she has spent = [tex] \frac{3}{7} x [/tex]
As per given in question, she has used 180 minues, so
[tex] \frac{3}{7} x = 180 [/tex]
Cross multiplying
[tex] 3x = 180*7 [/tex]
[tex] 3x = 1260 [/tex]
Dividing 3 in both sides
x = 420
Means she had monthly 420 minutes : Answer
Method 2 :
[tex] \frac{3}{7} [/tex] of her total monthly minutes will be = 180
So, 1 or say complete month total minutes will be = [tex] \frac{180}{\frac{3}{7} } [/tex]
So, 1 month total minutes will be = [tex] \frac{180*7}{3} = 420 [/tex]
So, the answer is 420 minutes : Answer
Hope it will help :)
