1.denise wanted to estimate the capacity of a bucket.she found that were 20 droplets of water leaked from a water tap for every two minutes and the volume of each drople was about0.2cm③.she then used the bucket to collect the water leaked from 9am to 5am,and the water collected filled 3/4 of the bucket.
(a)estimate the capacity of the bucket
(b)describe the estimation strategy used by denise and suggest one method to reduce the error of her estimation.
2.what fraction of a right angle is each of the following angles?
(a)24° (b)110°

中文回答还是英文
第一个20*0.2=4
4*30=120
120*3/4=160
answer：the capacity of the bucket is 160ml
第二个：she can calculation how much water does the tap drop one minute and then
calculation the capacity of the bucket ,then the reslut will be more accurate i think
第三个 i choose A
