Divide 800ml into ratio 3:7
Black_prince [1.1K]
Simply take the numerator (3) and denominator (7) and add them together. 

3+7 = 10, which means that the ratio will provide parts that are in multiples of 10 depending on the total

so take 10x = 800 

x = 80.

Then multiply this by the numerator and denominator 

3*80/7*80 = 240/560.

A farmer estimated that there were 25 gallons of water left in a tank. If this is an underestimate by 16%, how much water was ac
djyliett [7]

Answer:

The actual water in the tank is 29.76 gallons.

Step-by-step explanation:

It is given that the farmer estimated amount of water is 25 gallons.

It is also given that he underestimate the water in tank by 16%.

Let the actual water in tank be x.

(1-\frac{16}{100})x=25

(\frac{100-16}{100})x=25

84x=25\times 100

x=\frac{2500}{84}

x=29.7619

x\approx 29.76

Therefore the actual water in the tank is 29.76 gallons.
