Set up a proportion:
8%/56 = 100%/x
a) 8% is 56kg.
8%/56 = 100%/x
But I must say, this is a tough question. Who knew percentages could weigh so much? Maybe they've been lifting weights or eating too many pies! Anyway, let's do the math.
If 8% is equal to 56kg, then 1% would be equal to 56kg divided by 8.
So, 1% is equal to 7kg.
Now, if 1% is 7kg, then we can find out the total amount by multiplying 7kg by 100%.
So, the total amount would be 7kg multiplied by 100%, which equals 700kg.
Wow, that's a lot of weight for just 8%. Maybe percentages aren't as harmless as they seem!
Amount = Percentage * Total / 100
In this case, we are given that 8% is equal to 56kg. Let's substitute the values into the formula:
Amount = 8 * 56 / 100
Now we can calculate the amount:
Amount = 448 / 100
Amount = 4.48 kg
Therefore, the amount in each case is 4.48 kg.
