8/9 - 1/5=
how do i get the answer please explain dont just give answer please thanks
When adding or subtracting fractions, you must always use a common denominator.
The easiest way to determine that denominator is simply to multiply them: 9 * 5 = 45.
Multiply each fraction by a fraction that is equivalent to 1, but will result in the same
denominator. For this problem, multiply the first fraction by 5/5, and multiply the
second fraction by 9/9. Both 5/5 and 9/9 are equal to 1, so you are NOT changing
the VALUE of the fractions, merely their representation.
(8/9) * (5/5) - (1/5) * (9/9)
When multiplying fractions, multiply the numerators to get the new numerator, and
multiply the denominators to get the new denominator.
(8/9) * (5/5) - (1/5) * (9/9)
(8 * 5) / (9 * 5) - (1 * 9) / (5 * 9)
40/45 - 9/45
Now, simply subtract.
40/45 - 9/45
31/45
