Hi,
seems simple but it is not for me. I am trying to find somethinig that fits the answer given but nothing so far.
is there a way to start attacking this problem quickly without so much trying?
thanks in advance for any hint,
eddy

simplifying both sides
23/12+x=25/82 3/12 + x = 25/8(9/4)x=21/8(9/4)x= 21/8clearing the x by multiplying by the multiplicative inverse
(4/9)(9/4)x=(4/9)(21/8)(4/9) * (9/4)x = (4/9)* (21/8)7/6=11/67/6 = 1 1/6
 
so the missing value is 6?.
But the result is 1 1/6
so when I replace the value found for x doesn't equate to 2 5 /8 ??
 
simplifying both sides
23/12+x=25/82 3/12 + x = 25/8(9/4)x=21/8(9/4)x= 21/8clearing the x by multiplying by the multiplicative inverse
(4/9)(9/4)x=(4/9)(21/8)(4/9) * (9/4)x = (4/9)* (21/8)7/6=11/67/6 = 1 1/6
231223122\frac{3}{12}\neq \frac{23}{12} and 2582582\frac{5}{8}\neq \frac{25}{8}. Try again.
 
23/12+x=25/82 3/12 + x = 2 5/8simplifying
27/12+x=21/827/12 + x = 21/89/4+x=21/89/4 + x = 21/8
now subtractin' 9/4 from both sides
x+9/49/4=21/89/4x + 9/4 - 9/4 = 21/8 - 9/4subtracting the fractions on the right hand side
x=3/8x =3/8
checking
23/12+3/8=25/82 3/12 + 3/8 = 2 5/8simplifying
21/4+3/82 1/4 + 3/89/4+3/89/4 +3/821/821/8=25/8= 2 5/8
 
23/12+x=25/82 3/12 + x = 2 5/8simplifying
27/12+x=21/827/12 + x = 21/89/4+x=21/89/4 + x = 21/8
now subtractin' 9/4 from both sides
x+9/49/4=21/89/4x + 9/4 - 9/4 = 21/8 - 9/4subtracting the fractions on the right hand side
x=3/8x =3/8
checking
23/12+3/8=25/82 3/12 + 3/8 = 2 5/8simplifying
21/4+3/82 1/4 + 3/89/4+3/89/4 +3/821/821/8=25/8= 2 5/8
Eddy, you should learn how to write fractions in LaTex. Copy and paste the following line into the "Insert math" screen. Adapt a and b to your needs.
\frac{a}{b}
You are correct, x=38x=\frac{3}{8}. Now, compare that to the OP.
38=3\frac{3}{8}=\frac{3}{\square}

You don't need the $ signs..........................................................................................[$ signs were removed from response #11]
You haven't answered your FIND. What's the value in the box?
