8/9 x 9/10
8/9 x 9/10 = 72/90 = 4/5
To multiply fractions, you need to multiply the numerators together and multiply the denominators together.
Step 1: Multiply the numerators (top numbers) together:
8 x 9 = 72
Step 2: Multiply the denominators (bottom numbers) together:
9 x 10 = 90
Step 3: Write the result as a fraction with the product of the numerators over the product of the denominators:
72/90
Step 4: Simplify the fraction if possible. In this case, both the numerator and denominator can be divided by 18:
72 ÷ 18 = 4
90 ÷ 18 = 5
So the simplified fraction is 4/5.
To multiply two fractions, you simply multiply the numerators (top numbers) to get the new numerator, and multiply the denominators (bottom numbers) to get the new denominator.
In this case, to multiply 8/9 and 9/10, you would multiply the numerators 8 and 9, and the denominators 9 and 10.
8/9 * 9/10 = (8 * 9) / (9 * 10)
The numerator is 72 (8 * 9), and the denominator is 90 (9 * 10).
Therefore, the answer is 72/90.
