This spinner below is divided into 10 equal sections what is the probability of spsinning it and landing on a number that is divisable by 5

Between 1 and 10, only two numbers are divisible by 5, and those are 5 itself, and 10.

Those two possibilities, out of the total of ten possibilities, gives us a probability of 2/10

You can simplify that probability fraction by dividing the numerator and denominator by 2.

1/5

(or 20% if you prefer percentages).
