Answer:53 dresses
Step-by-step explanation:
First of all..if one kid required 2 1/4m of cloth,what about 119 1/4m of cloth?
So u take 119 1/4m of cloth and divide it by 2 1/4m of cloth.
Then change the mixed numbers into improper fractions.
So the question will be 477/4 m divided by 9/4 m.
The second improper fraction (9/4)m will be reciprocated to be (4/9)m.
Afterwards,take 477/4 m and multiply it by 4/9 m.
The result will be 53 dresses.
[120 + 12 : 3*30] : 20 + 100= [120+120]: 20 +100= 240 : 20 + 100
= 12 + 100=112
1256.64 is the area, because you use this equation- A=πr^2
D because the total of marbles is 5 and the green marbles are 2
