Answer:
9/20
Step-by-step explanation:
first you have to make 1 1/4 an improper fraction so since the denominator is 4 you add 4 to the numerator which is 1 so your fraction would be 5/4.
Second you make the denominators the same so you have to multiply them together. but since your multiplying the denominators you have to multiply the numerator as well. so for 5/4 you would multiply both the numerator and denominator by 10 so your fraction will now be 50/40. now you multiply 8/10 by 4 so your new fraction is now 32/40
Third you subtract. you only have to subtract the numerators so 50-32 is 18 so your answer is 18/40
Last you need to simplify the highest number you can divide both of them by is 2 so now you divide 18 by 2 which makes 9 then you divide 40 by 2 which is 20 so your answer is 9/20
Sorry i'm not the best at explaining things but i tried my best
