how do i find 1/3 of 9
2/5 of 25
in math, the word of means times so you would multiply 1/3 x 9 & 2/5 x 25. To set these problems up, you would change the whole numbers (9 & 25) into fractions, so you would have 1/3 x 9/1 for the first one, and 2/5 x 25/1 for the second one. When you line them up on your paper, you can either multiply straight across the tops & the bottoms then reduce, or you can cross-cancel before you multiply. Have you done cross-canceling?
You actually don't need to do all of the work Jesse has said. I'll show you a shortcut. Take the denominator (bottom part of a fraction) and divide it by your whole number. Then multiply that by the numerator (top part of a fraction). You can do it really fast in your head.
1/3 of 9 = 9/3=3x1=3
2/5 of 25= 25/5=5x2=10
Take the denominator (bottom part of a fraction) and divide your whole number by it. Then multiply that by the numerator (top part of a fraction).
To find 1/3 of 9, you multiply 9 by 1/3.
Step 1: Multiply the numerator (1) by the number (9).
1 x 9 = 9
Step 2: Multiply the denominator (3) by the number (1).
3 x 1 = 3
Step 3: Write the result as a fraction, with the numerator (9) over the denominator (3).
1/3 of 9 = 9/3 = 3
Therefore, 1/3 of 9 is equal to 3.
To find 2/5 of 25, you multiply 25 by 2/5.
Step 1: Multiply the numerator (2) by the number (25).
2 x 25 = 50
Step 2: Multiply the denominator (5) by the number (1).
5 x 1 = 5
Step 3: Write the result as a fraction, with the numerator (50) over the denominator (5).
2/5 of 25 = 50/5 = 10
Therefore, 2/5 of 25 is equal to 10.
