Question

$\purple{3 - 8 + 1 \div 7 \times 5 - 1 = ?}$















​

Answer 1

Answer:

-5.29

Step-by-step explanation:

You have to solve this according to BODMAS theory.

That is,

B ⇒ Brackets

O ⇒ Of

D ⇒ Division

M ⇒ Multiplication

A ⇒ Addition

S ⇒ Subtraction

Let us solve now.

3 - 8 + 1 ÷ 7 × 5 - 1

3 - 8 + 0.142 × 5 - 1

3 - 8 + 0.71 - 1

-5 + 0.71 -1

-4.29 - 1

-5.29

Hope this helps you :-)

Answer 2

Answer:

The answer is -5.29.

Step-by-step explanation:

Solution :

To solve the above equation we will follow the BODMAS rule.

• $\small\pink\bull$ BODMAS is an order of mathematic operations.
• $\small\pink\bull$ BODMAS rule is to be followed while solving expressions in mathematics.

It stands for :

$\quad\begin{gathered} \small \begin{array}{l} \star \: \rm B= bracket \\\star \: \rm O= order \: of \: power \: \\\star \: \rm D= division \\\star \: \rm M= multiplication \\ \star \: \rm A= addition \\ \star \: \rm S=subtraction \end{array}\end{gathered}$

Solving this question by bodmas rule :

${ = \tt{3 - 8 + 1 \div 7 \times 5 - 1 }}$

${ = \tt{3 - 8 + \dfrac{1}{7} \times 5 - 1 }}$

${ = \tt{3 - 8 + 0.142\times 5 - 1 }}$

${ = \tt{3 - 8 + 0.71 - 1 }}$

${ = \tt{ - 5 + 0.71 - 1 }}$

${ = \tt{ - 4.29 - 1 }}$

${ = \tt{ - 5.29 }}$

$\star\underline{\boxed{\tt{\red{ - 5.29 }}}}$

Hence, the answer is -5.29.
