A florist orders sunflowers every 6 days, starting from the sixth day of the year, and daisies every 4 days, starting from the fourth day of the year. When (or on which day) will she orders both kinds of flowers on the same day? *

Respuesta :

Answer: 12th day

Step-by-step explanation:

Given , A florist orders sunflowers every 6 days and  daisies every 4 days.

When it started from same day, then the next day she orders both kinds of flowers on the same day will be LCM (6,4), where LCM = Least Common Multiple.

Prime factorization:

6 = 2 x 3

4 = 2 x 2

LCM(6,4) = 2 x 2 x 3 = 12

Hence, she will order both kinds of flowers every 12 days.

The day she will order both kinds of flowers on the same day is 12th day of the year

Given:

Sunflower order = every 6 days

Daisies order = every 4 days

Find the lowest common multiple of 6 days and 4 days

6 days = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60

4 days = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60

The lowest common multiple of 6 days and 4 days is 12 days

Therefore, the day she will order both kinds of flowers on the same day is 12th day of the year
