Answer:

60

Step-by-step explanation:

How many multiples of 4 is less than 300?

We need to divide the biggest multiple of 4 less than 300 to 4

296 ÷ 4 = 74

How many multiples of 4 and 5 is less than 300?

The lowest number that is divisible by 4 and 5 is 20

We need to divide again the biggest multiple of 20 less than 300 to 20

280 ÷ 20 = 14

Subtract the multiples of 4 to the multiples of 4 and 5

74 - 14 = 60 is the number of positive numbers less than 300 that are divisible by 4 but not 5.
