Two methods can be used here; take your pick.
1) Multiply 2 times the number, multiply 1/2 times the number, add the results. Example: 2 1/2 times 20 = (2 x 20) + (1/2 x 20) = 40 + 10 = 50.
2) Convert the mixed fraction into an improper fraction, than multiply. Example: 2 1/2 x 20 = 5/2 x 20 = 100/2 = 50.

How do you find the one fourth half and three fourth of two numbers?
one fourth: divide the number by 4, or multiply it by 0.25half: divide the number by 2, or multiply it by 0.5 three fourths: multiply the answer to the first by 3, or multiply the original number by 0.75
When two numbers multiply the result is increases but when you mutiply .5 and.5 the answer get decreases that is .25 how?
The number .5 means half. So, if you take half of something, that is less than the entire thing, right? And half of half is a quarter. Multiplication only makes numbers larger when you multiply numbers that are greater than one. If you multiply by one the number doesn't change. If you multiply by less than one, you make the number smaller.
