These two fractions do not have the same denominators (lower numbers), so we must first find a common denominator of the two fractions, before subtracting them. For the denominators here, the 8 and 5, a common denominator for both is 40. search how to subtract fractions on google, and click on subtract two fractions-Web math, there you can type your problem, and it will give you step by step on how to do it.
