Question

1) -2 + 1/2 * (-3/5) + (-1/10) *9 2) -3/4 : 1/4 + 7/10 : (-1/5) ОБЯЗАТЕЛЬНО С РЕШЕНИЕМ

Answer 1

1)-2+$\frac{1}{2}$*(-$\frac{3}{5}$)+(-$\frac{1}{10}$)*9=-2-$\frac{3}{10}$-$\frac{9}{10}$=-3$\frac{1}{5}$

2) -$\frac{3}{4}$:$\frac{1}{4}$+$\frac{7}{10}$:(-$\frac{1}{5}$)=-3+3$\frac{1}{2}$=$\frac{1}{2}$

Answer 2

1) -2 + 1/2 * (-3/5) + (-1/10) * 9 First, we simplify the multiplication and division within the parentheses: -2 + 1/2 * (-3/5) + (-9/10) Next, we multiply the fractions: -2 + (-3/10) + (-9/10) Now, we add the fractions: -2 + (-12/10) Finally, we simplify the result: -2 - 1.2 -3.2

2) -3/4 ÷ 1/4 + 7/10 ÷ (-1/5) First, we divide the fractions: -3/4 * 4/1 + 7/10 * (-5/-1) Simplify the fractions: -3 + 7/10 * 5 -3 + 7/2 Now, we add the fractions: -3 + 3.5 0.5

So, the solutions are: 1) -3.2 2) 0.5
