7. $\frac{1}{2}+\frac{1}{3}\frac{1}{5}$

8. 0.1+0.150.2

Step-by-step explanation:

Given:

Three sides of the triangles are given.

For Question 7

1/2 _ 1/3 _1/5

For Question 8

0.1 _ 0.15 _ 0.2

We need to use >, <, and + signs to write inequalities for the relationships among the sides of the triangles.

Solution:

Part 7.

Property of the triangles.

Sum of two side of triangles must be greater than third side.

So, first, second and third side of the triangle is $\frac{1}{2}, \frac{1}{3}\ and\ \frac{1}{5}$

$\frac{1}{2}+\frac{1}{3}\frac{1}{5}$

$\frac{5}{6}\frac{1}{5}$

So, its satisfy the triangle rule.

Therefore, Inequality is $\frac{1}{2}+\frac{1}{3}\frac{1}{5}$

Part 8.

Property of the triangles.

Sum of two side of triangles must be greater than third side.

So, first, second and third side of the triangle is $0.1, 0.15\ and\ 0.2$

0.1+0.150.2

0.250.2

So, its satisfy the triangle rule.

Therefore, Inequality is 0.1+0.150.2
