Numerically, what you said is:
1/2 x 2/3 x 3/4 x 4/5 x 5/6 x 6/7 x 7/8 x 8/9 x 9/10 x 1000
By rearranging the numerators, i can get:
2/2 x 3/3 x 4/4 x 5/5 x 6/6 x 7/7 x 8/8 x 9/9 x 1/10 x 1000 = 1000/10 = 100
In case you don't know, the sign "/" also means divide. And also, you can move the numerators of fractions only when the fractions are multiplied or divided to one another (it cannot be used during addition and subtraction of fractions)
One hundred.
3/4 and 5/6. The least common multiple of the two denominators is 12. so the fractions cane be written as 9/12 and 10/12. Since the denominators are the same just compare the numerators and see which one is bigger. 5/6 is bigger than 3/4
