Question

Evaluate the expression shown below and write your answer as a fraction in simplest form(1/10-2/3) ÷ 0.5

Answer 1

`(-17)/(15)`

Explanation:

When solving this problem you must follow PEMDAS, so parentheses should go first. To solve 1/10 - 2/3, first, find the common denominator. In this case, that is 30. Then, subtract,
`(3)/(30) - (20)/(30)`. This equals -17/30. Finally, divide by 0.5. To do this remember that dividing by half is the same as multiplying by 2. Doing
`(-17)/(30) *2` equals
`(-17)/(15)`.
