What value will replace the question mark in the following equations ?
(i) 5172.49 + 378.352 + ? = 9318.678 (ii) ? − 7328.96 = 5169.38
Answer: B
Isolate the question mark in each equation.
(i)
\[ ? = 9318.678 - 5172.49 - 378.352 = 3767.836 \]
(ii)
\[ ? = 5169.38 + 7328.96 = 12498.34 \]
Note the direction of each operation: the first needs subtraction because the unknown sits on the adding side, and the second needs addition because it is being subtracted from.
