There is a string of red and blue lights strung around a window. the red lights blink every 3 second and the blue lights every 5 seconds. how many times will they blink at re same time in one minute?

Find the lowest common multiple of 3 and 5, that is 15

the lights will blink together every 15 seconds

in 1 minute blink together = 4 times

that is at 15, 30, 45 and 60

They will blink 4 times together in one minute.

Step-by-step explanation:

The amount it takes for them to blink together is the least common multiple between the time it takes for each of them to blink together.

The red light blinks each 3 seconds.

The blue light blinks each 5 seconds.

The least common multiple between 3 and 5 is 15. So they will blink together each 15 seconds.

Each minute has 60 seconds. So they will blink 60/15 = 4 times together in one minute.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

answer: 2530
