3 decimeter is the same as 30 centimeters, because 1 decimeter=10 centimeter, so if you convert 3 decimeter into centimeters, you'll get 30, 3×10=30cm
30cm=30cm, so your answer is both are equal.

Answer:
40 ft
Step-by-step explanation:
The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.
tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft
The tree is 40 feet tall.

Answer:
a. 80%
b. £34
c. £340
Step-by-step explanation:
a. We are given that Mrs Trent spent 20% of her weekly wage on food. This means she would have 80% of her weekly wage left with her.
b. 10% of Mrs Trent weekly wage:
If 20% = £68
10% = (10*68)/20 = £34
c. Let x represent weekly wage of Mrs Trent
Given that she spends £68 of x (weekly wage) on food, which is 20% of x.
This means that, 20% of x = £68
Let's find her weekly wage, x:
![\frac{20}{100} * x = 68](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B100%7D%20%2A%20x%20%3D%2068%20)
![0.2x = 68](https://tex.z-dn.net/?f=%200.2x%20%3D%2068%20)
Divide both sides by 0.2
x = 340
Her weekly wage is £340.
