Correct option is C
Given: 98–49÷7+74×55=3
From Option A.) = and +
the modified equation becomes:
98–49÷7=74×55+3
98-7=74×55+3
91=4070+3
91 ≠ 4073(not balances the equation)
From Option B.) = and ÷
the modified equation becomes:
98–49=7+74×55÷3
49=7+74×18.33
49=7+1356.42
49 ≠1363.42(not balances the equation)
From Option C.) = and ×
the modified equation becomes:
98–49÷7+74=55×3
98-7+74=55×3
172-7=165
165=165 (Balances the equation)
From Option D.) = and −
the modified equation becomes:
98=49÷7+74×55-3
98=7+74×55-3
98=7+4070-3
98=4077-3
98 ≠4074(not balances the equation)
Thus, correct option is (c).
