3. Question
1 pointsIf ‘–’ stands for division, ‘+’ for
multiplication, ‘÷’ for subtraction
and ‘×’ for addition, which one of
the following equations is correct?
(1) 6 ÷ 20 × 12 + 7 – 1 = 70

(3) 6 – 20 ÷ 12 × 7 + 1 = 57
(4) 6 + 20 – 12 ÷ 7 – 1 = 38CorrectOption (1)
Given expression
6 ÷ 20 × 12 + 7 – 1 = 70
After conversion
6 – 20 + 12 × 7 ÷ 1 = 70
or, 6 – 20 + 84 = 70
or, 90 – 20 = 70
or, 70 = 70IncorrectOption (1)
Given expression
6 ÷ 20 × 12 + 7 – 1 = 70
After conversion
