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

The given number sentence is simplified as 1 3/5

Step-by-step explanation:

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

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 answer is written in the form of

⇒ 1 3/5

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
