On a average day a horse might drink 50 la sheep might drink 4 l and a chicken might drink 200ml how much water would a farm with 3 horses 15 sheep and 12 chickens need for a day

Horse - 50l

sheep-4l

chicken-200ml

first you have to convert all the symbols into one, so we'll convert liters into milliliters,

1000ml=1l

horse = 50 * 1000=50000ml

sheep=4*1000=4000ml

chicken = 200ml

so now we have to multiply them by the number of animals,

h=50000ml*3=150000ml

s=4000*15=60000ml

c=200*12=2400ml

now add them together,

150000+60000+2400=212400ml

convert it into litres,

212400:1000=212.4l

answer = 212.4 l
