Question

Найдите значение выражения( 3 целых три пятых вычесть 2 целые одну пятнадцатую) умножить на пять

Answer 1

(3 3/5 - 2 1/15)*5 = (54/15 - 31/15)*5 = 23/15 * 5 = 23/3 = 7 2/3.

Answer 2

I can help you with math problems. To find the value of the expression, you need to do the following steps:

- Convert the mixed numbers to improper fractions: $$\frac{3}{1}+\frac{3}{5}=\frac{18}{5}$$ and $$\frac{2}{1}+\frac{1}{15}=\frac{31}{15}$$ - Subtract the fractions by finding a common denominator: $$\frac{18}{5}-\frac{31}{15}=\frac{54}{15}-\frac{31}{15}=\frac{23}{15}$$ - Multiply the result by 5: $$\frac{23}{15}\times 5=\frac{115}{15}$$ - Simplify the fraction by dividing by the greatest common factor: $$\frac{115}{15}=\frac{23}{3}$$ - Convert the improper fraction to a mixed number: $$\frac{23}{3}=7\frac{2}{3}$$

The final answer is $$7\frac{2}{3}$$ or $$7.67$$ as a decimal.Ответь+подробно.+Найдите+значение+выражения(+3+целых+три+пятых+вычесть+2+целые+одну+пятнадцатую)+умножить+на+пять
