Given
1. 4 x 1/7
2. 12 x 2 5/6
procedure

1. The answer is 4 x 1/7 is less than 4

2. The answer is 12 x 2 5/6 is greater than 12
This does not appear to make sense, could you perhaps add signs such as multiplication, division, etc.
There are 80.5 tens in 805
3900 - 3867 = 33kg about the size of a little boy
Answer:
6 units²
Step-by-step explanation:
The coordinates (1,1) (1,4) (5,1) form a right triangle as shown in the graph below
The base is is (1,1) and (5,1) so the length is 5-1 or 4 units
The height is (1,1) and (1,4) so the height is 4-1 or 3 units
Area of a triangle is given by
A = 1/2 bh
= 1/2 (4*3)
= 1/2 *12
= 6 units^2
