There is no visible operator between 4/9 and 5/6.
= 4 6 -- x -- 9 5 = 24 --- 45
42/9 * 4/5
1.1
5/6 x 9/2 = 45/12 which reduces to 15/4 or 3 3/4
5/6 + 4/6= 9/6 which is also 1 1/2. You add 5+4 which would make it 9/6, 6 goes into 9 once leaving 3/6 which is 1/2, so 1 1/2.
The sum of 5/6 and 4/9 is 1 5/18
6 - 5/9 = 5 and 4/9
= 4 6 -- x -- 9 5 = 24 --- 45
(5/6) + (4/6) = 9/6 = 1 and 1/2
42/9 * 4/5
1.1
5/6 + 4/9 = ? 15/18 + 8/18 = 23/18 or 1 5/18 or 1.28
4 4/9
5/6 x 9/2 = 45/12 which reduces to 15/4 or 3 3/4
4/5 x 5/6 = 20/30 or 2/3 2/3 x 9/8 = 18/24 or 3/4
5/6 + 4/6= 9/6 which is also 1 1/2. You add 5+4 which would make it 9/6, 6 goes into 9 once leaving 3/6 which is 1/2, so 1 1/2.
LCD(9, 6) = 18
