The area is 1/2(b)(h).

We apply this to the base of the triangle to get 3x (0.5*3=1.5), then multiply it by 2x (the height) to get 3x^2

The area of a triangle is always:

A=bh/2 (base times the height divided by 2)

A=3x(2x)/2

A=6x^2/2

A=3x^2

Alison knits 1/10 of scarf in 4/5 of an hour. what fraction of a scarf can alison knit in 1 hour? and how do u solve it?

pav-90 [236]

For this case we can make the following rule of three:
1/10 scarf ------> 4/5 hour
x ------------------> 1 hour
Clearing the value of x we have:
x = (1 / (4/5)) * (1/10)
Rewriting we have:
x = (5/4) * (1/10)
x = 5/40
x = 1/8
Answer:
A fraction of a scarf that alison can knit in 1 hour is:
x = 1/8
