rewrite the statement 19 x 7 ÷ 2 x 6 + 1 by including 2 pairs of brackets to make the total value equal to 2
Answers
Answer:
78
Step-by-step explanation:
19×7=133
133+13=156
156÷2=78
rewrite the statement 19 x 7 ÷ 2 x 6 + 1 by including 2 pairs of brackets to make the total value equal to 2. Rewritten expression is: (19 + 7) ÷ (2 x 6 + 1)
First of all, the original expression would be 19 + 7 ÷ 2 X 6 + 1.
If we follow the BODMAS procedure then we would end up getting 41.
This is because we would evaluate division operation first, followed by multiplication, then addition. So,
division of 7 and 2 = 3.5
∴ 19 + 3.5 X 6 + 1
= 19 + 21 + 1 [As multiplication operation is done next and 3.5X6 = 21]
= 41.
But we know that bracket operation has the highest priority. So any operations within brackets would be treated first and internally in these brackets, BODMAS would be applicable wherever necessary.
To get the answer as 2, we put the two brackets in this manner:
(19 + 7) ÷ (2 X 6 + 1) .
If we evaluate now, we see that (19+7) and (2X6 + 1) are treated with the highest priority as they are in brackets. So, we get,
26 ÷ (12 + 1) [Multiplication is done before addition].
= 26 ÷ 13
= 2
Through this pairing, we get 2.
