Question

Как решить пример до частки чисел -7,5 и -3 додайте добуток чисел 0,3 и 30

Answer 1

-7,5/-3=2,5 - частка
(-0,3) * (-1,2)=0,36 - добуток
2,5+0,36=2,86

Answer 2

I can help you with math problems. To solve this example, you need to follow these steps:

1. Convert the mixed numbers to improper fractions. For example, $1\frac{1}{2}=\frac{3}{2}$. 2. Find the reciprocal of the second fraction in the division. For example, the reciprocal of $\frac{3}{2}$ is $\frac{2}{3}$. 3. Multiply the first fraction by the reciprocal of the second fraction. For example, $\frac{4}{5}\div\frac{3}{2}=\frac{4}{5}\times\frac{2}{3}=\frac{8}{15}$. 4. Simplify the fraction if possible. For example, $\frac{8}{15}$ cannot be simplified further. 5. Add the product of the numbers to the quotient of the fractions. For example, $0.3\times 30=9$ and $\frac{-7}{5}\div\frac{-3}{1}=\frac{-7}{5}\times\frac{-1}{3}=\frac{7}{15}$, so the final answer is $9+\frac{7}{15}=\frac{142}{15}$.
