Answer:
8
Step-by-step explanation:
1 1/2 + 3/4 = 2 1/4
2 1/4 ÷ 1/8 = 9/32
2 1/4 ÷ 9/32 = 8
The day is 35 when they get to see each other at the beach after finding the LCM of the numbers 7 and 5.
It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
Last summer, Karl went to the beach every 5 days.
Antonia went to the beach every 7 days.
To find the day they get to see each other at the beach:
Find the LCM(lowest common factor) of 7 and 5:
7: 7, 14, 21, 28, 35,
5: 5, 10, 15, 20, 25, 30, 35
The common number is 35.
Thus, the day is 35 when they get to see each other at the beach after finding the LCM of the numbers 7 and 5.
