2 over 4 can be simplified to 1 over 2.
63/70 = 9/10
63/70 simplifies to 9/10.
28/63 = 4/9 in its simplest form
7 8/9 You take the 7 and times by 9. 7x9=63. 63+8= 71/9
No but as a decimal 9/20 is equivalent to 0.45
No.
6/7 x 9/9 = 54/63 80/9 x 7/7 = 560/63 54/63 + 560/63 = 614/63
Yes.
Yes.
It is 1.
One over ten.
7/9 - 4/7 = 49/63 - 36/63 = 13/63
9/63 = (9÷3)/(63÷3) = 3/21 = (3÷3)/(21÷3) = 1/7 but as 6+3 = 9, 63 is divisible by 9, so: 9/63 = (9÷9)/(63÷9) = 1/7
43/360
It is already simplified.
one half.
