I need help on this:

Solve this number sentence: 2-4/5 x 1/2 = ________ *simplify answer*

1. 1 2/8
2. 7/2
3. 1 2/5

Answer 1

The given number sentence is simplified as 1 3/5

Explanation:

The given number sentence is 2-4/5 x 1/2

• In order to solve this, the operations must be performed based on the BODMAS rule.
• This means that, the operations should be performed in the order of Bracket, Of, Division, Multiplication, Addition and Subtraction.

Here, based on that above rule, the multiplication must be done in the first step and then subtraction should be done in the next step.

⇒ 2 - 4/5 × 1/2

⇒ 2 - 4/10

⇒ 2 - 2/5

Therefore, the given expression is reduced to 2- 2/5

cross multiply the denominator 5

⇒ (10-2) / 5

⇒ 8/5

Now, the expression is reduced to single term 8/5.

To further reduce the term, divide 8 by 5.

• The quotient is 1.
• The remainder is 3.
• The divisor is 5.

The answer is written in the form of
`Quotient(Remainder/ divisor)`

⇒ 1 3/5
