4 answers
i dont get it
ratio
8+7+5 = 20 equal parts to be shared
100/20 = 5
so the "7" person gets 7*5 = 35
8:7:5 = 40:35:25
100/20 = 5
so the "7" person gets 7*5 = 35
8:7:5 = 40:35:25
Total share 100 kg
The ratio is 8:7:5
Let the common factor be x
Share of first person is 8 x
Share of second person 7 x
Share of third person is 5 x
Total share:
8 x + 7 x + 5 x = 20 x
20 x = 100 kg
x = 100 kg / 20
x = 5 kg
Share of first person is 8 • 5 kg = 40 kg
Share of second person 7 • 5 kg = 35 kg
Share of third person is 5 • 5 kg = 25 kg
Person wit 7 shares get 35 kg
The ratio is 8:7:5
Let the common factor be x
Share of first person is 8 x
Share of second person 7 x
Share of third person is 5 x
Total share:
8 x + 7 x + 5 x = 20 x
20 x = 100 kg
x = 100 kg / 20
x = 5 kg
Share of first person is 8 • 5 kg = 40 kg
Share of second person 7 • 5 kg = 35 kg
Share of third person is 5 • 5 kg = 25 kg
Person wit 7 shares get 35 kg
