1/3 is greater than 2/7 because if you put them the same denominator in this case it would be 21 you would multiply 1/3 by 7 and 2/7 by 3 so 1/3 would be 7/21 and 2/7 would be 6/21 so yes 1/3 is greater than 2/7
Age of tom=t
age of john=j
age of andy=a
t<a
if j is not older than t, then he is less than or equal to t so
j ≤ t
but there is an oldest so therefor we assume that j < t
t < a
j < t
subsitute
j<t<a
andy is oldest
tom is second
john is youngest
Both work but if it is a decrease using the first one it will be -xx%
Hope this helps :)
Given:
Width = 2 ft
Parallel bases: 4 ft and 6 ft.
The area is (1/2)(Sum of the bases) x Width.
Therefore the area is
A = (1/2)*(4 + 6)*2
= (1/2)*10*2
= 10 ft²
Answer: 10 ft²
Is there a picture I can see
