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.
Multiply the length and width, and divide that number by two. Half of a 5x5 square: 5 times 5 = 25. 25/2= 12.5 Don't forget it's "units squared"!
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
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.
Finding 250 percent of a number is the same as finding 2.5 times the number. Therefore, to find 250 percent of a number, multiply the number by 2.5. For example, 250 percent of 10 is equal to 2.5 x 10 = 25.
They are 11 times 17 = 187
you multiply length times width and if its a triangle you multiply length times width and divide by two or cut in half (:
...but if you multiply a whole number by a half the result decreases. Half of anything is less than that thing!
Find the common denominator of the two fractions, which will give us 6. Multiply the numerator by the number of times
divide 62 by 2 = 31
Square - multiply same number two times Cube - multiply same number three times 7 X 7 X 7 = 343 !!!

If you multiply the fraction three-fourths by two you will get six-fourths. If you change that improper fraction to a mixed fraction you will get one and two-fourths. The two-fourths reduces to one-half. There fore three-fourths times two is one and a half.
To multiply whole number by 100 simply add two zeros to the right end. Example: 341 times 100 is 34100.
