Answer:

a=6, b=5.5

Step-by-step explanation:

By looking at the sides of the triangles it can easily be seen that some of the sides match up. Side b is similar to the side of 11 and same with side a and the side of 3. Since one side is 16 and the other side on the smaller triangle is 8, the bigger triangle is twice as large than the smaller one. So 3 x 2 = 6 and 11 / 2 = 5.5

Here are two sums.

Answer:

6/7 - 1/3

Step-by-step explanation:

You know that 1/2=0,5

Then, you have to solve the two sums:

2/15+1/3=((2*3)+(15*1))/(15*3)=(6+15)/45=21/45=0,4666=0,47

6/7-1/3=((6*3)-(7*1))/(7*3)=(18-7)/21=11/21=0,5238=0,52

You now know what number of 0,47 and 0,52 is closer to 0,5; which is 0,52

0,47 is to 0,03 from 0,5

0,52 is to 0,02 from 0,5
