well, clearly the LCD from the denominators of 5 and 10 is just 10, thus

\bf \stackrel{\textit{Sue}}{\cfrac{2}{5}}+\stackrel{\textit{Sally}}{\cfrac{4}{10}}\implies \stackrel{\textit{LCD of 10}}{\cfrac{(2)2~~+~~(1)4}{10}}\implies \cfrac{2+4}{10}\implies \cfrac{6}{10}\implies \stackrel{\textit{simplified}}{\cfrac{3}{5}}

Find 7512−(−334) . Write your answer as a mixed number in simplest form.
Savatey [412]

Answer:

7846

Step-by-step explanation:

two 'minus' signs cancel each other out and become an 'plus' sign

therefore

7512-(-334) = 7512 + 334

= 7846

I don't know why you wrote ' write your answer as a 'mixed number ' in 'simplest form'. A mixed number can only be formed when you have a fraction, an improper fraction no less, the answer is a whole number, and therefore cannot be written as a mixed number in simplest form. If I am wrong pls let me know and elaborate by what you mean by 'mixed number' in the comments.

I believe it may be a trick question, but who knows.

Examples of fractions expressed as a mixed number.

19/8 = 2 3/8

17/5 = 3 2/5
