To find the answer, we can first find the total number divisible by 7 of 50 and 500 separately:
50÷7 = 7.14...
there are 7 divisible for 50.
500÷7= 71.42...
there are 71 divisible for 500.
We can then deduct the number of divisible for 50 from 500 to find the answer:
71-7
=64
Therefore, the answer is 64.
Hope it helps!
