18 8/9
-6 3/5
"each" difference?
18 8/9 = 170/9 = 850/45
6 3/5 = 33/5 = 297/45
subtract to get 553/45 = 12 13/45
Thank you
44 3/8
-9 7/12
do it the same way:
44 3/8 = 355/8 = 1065/24
9 7/12 = 115/12 = 230/24
subtract to get 835/24 = 34 19/24
To subtract fractions, you need to have a common denominator. In this case, let's find the common denominator of 9 and 5, which is 45.
Now, let's convert each fraction to have the common denominator of 45:
18 8/9 = 18 * 9/9 + 8/9 = 162/9 + 8/9 = 170/9
-6 3/5 = -6 * 5/5 + 3/5 = -30/5 + 3/5 = -27/5
Now, we can subtract the fractions:
170/9 - 27/5
To subtract fractions, we need a common denominator. In this case, the common denominator is 45.
Now, let's convert the fractions to have a common denominator of 45:
170/9 is already in terms of 9, so we'll multiply the numerator and denominator by 5 to get:
(170 * 5) / (9 * 5) = 850/45
For -27/5, we'll multiply the numerator and denominator by 9:
(-27 * 9) / (5 * 9) = -243/45
Now, we can subtract the fractions with the common denominator:
850/45 - 243/45
To subtract the fractions, we subtract their numerators while keeping the common denominator:
(850 - 243) / 45 = 607/45
The final difference in lowest terms is 607/45.
