The weight of both cases of apples is 55 kg. If 5 kg is taken out of case a and put into case B, how much more is the weight of case B than that of case a? How to solve the equation
Suppose that there are x kg in total
55%x-7.5=(1-0.6)X
0.15X=7.5
X=50
There are two boxes of apples. After taking out 5 / 8 of box a and 3 / 5 of Box B, the weight of the remaining two boxes is equal. How many kg are there in each box?
emergency
Let box a be x kg and Box B be y kg
(1-5/8)X=(1-3/5)y
For two cases of apples of equal weight, take 25 kg out of box a and 7 g out of box B. at this time, Box B is three times the weight of box A. how many kg are there in each of the two cases?
Draw a line diagram, quick
25-7 = 18 (kg)
3-1=2
18 △ 2 = 9 (kg)
Box a 25 + 9 = 34 (kg)
Box B 9 × 3 + 7 = 34 (kg)
For two cases of apples, take one fourth from box a and one fifth from box B. the remaining mass of the two cases is the same. It is known that box a is originally 40 kg and Box B is several thousand kg
Answer: 37.5kg
30÷（1-1/5)=37.5
