vivado [14]

Remember when you learning about the "Least Common
Multiple" and you wondered when in the world you would
ever need to use it ?
Well, here you are !   Hello !

The next time they will cross the starting line together is the
LCM (Least Common Multiple) of 30 and 40 .

Do you remember how to find it ?
Here's one easy way: 

Count by 30s until you come to a number that's divisible by 40 .

Laura's first lap. . . . . . . . 30 seconds . . . not divisible by 40
Laura's two laps . . . . . . . 60 seconds . . . not divisible by 40
Laura's three laps. . . . . . 90 seconds . . . not divisible by 40
Laura's four laps. . . . . . 120 seconds . . . divisible by 40

Dima called her friend to tell her that she saved 30% on her new skirt at a discount store. Her friend told her that she could h
Olenka [21]
Since the rate of the other store is not given, let us just get the sales price of the skirt Dima bought from the discount store.

Original price : $54
Discount rate : 30%

$54 x 30% = $16.20 value of the discount
$54 - 16.20 = $37.80 discounted price.

Since Dima's friend told her she could have had a better deal at a different store, this means that the discount rate is higher than 30%. Let us assume that the discount is 35%

$54 x 35%  = $18.90 value of the discount
$54 - 18.90 = $35.10 discounted price.

Discount store: $37.80
Different store: $35.10

Different store sales price is cheaper by $2.70
