4.817+9.099+17.008=30.924
484.603-48.198=436.405

485-48=437
Just round each decimal to the nearest whole number and add or subtract
Unknown = x
the quotient of x and 12 is x/12 than 49 more than that is 53,
(x/12)+49=53, now use basic math and solve
-49 from both side,
x/12=4
*12 to both side,
x=48
therefore the unknown number is 48
A right triangle. Hope this helps.
