If $${a+b\over c+d}={16\over 15}$$

then what is a,b,c and d?

Or just, what is abcd=?

Another possibly dumb question my classmate made and we tried to solve.

If

$$\frac{a+b}{c+d}=\frac{16}{15}$$

then what is a,b,c and d?

Or just, what is abcd=?

Another possibly dumb question my classmate made and we tried to solve.

$$\frac{9+7}{10+5}=\frac{16}{15}$$

$$a=9,\ b=7,\ c=10,\ d=5$$

$$abcd=9\times 7\times 10\times 5=3150$$

It could be

$${1+15 \over 1+14}$$

And then abcd = 210...

This problem is probably unsolvable.
