How do you solve this? <br>Y x 49/36=7/12

Triss [41]

Divide both sides by 49/36 to get y by itself:

$\frac{7}{12} \div \frac{49}{36}$

$\frac{7}{12} \times \frac{36}{49} = \frac{254}{588}$

Simplify this fraction:

$\frac{254}{588} \div \frac{2}{2} = \frac{127}{294}$

Now you have your answer:

$y = \frac{127}{294}$

Paul's car will go 49 kilometers on 7 tanks. Paul wants to know how fuel efficient the car is. Please help by computing the rati

alisha [4.7K]

Answer:

7 : 1

Step-by-step explanation:

Paul's car goes 40 kilometers on 7 tanks.

Distance : Tanks

49 : 7

Fuel efficiency means the distance traveled by the car in one tank.

Therefore, we will reduce the ratio by dividing both sides by 7.

Distance : Tanks

$\frac{49}{7}$ : $\frac{7}{7}$

7 : 1

Therefore, car's fuel efficiency is 7 kilometers in one tank or the ratio between Distance traveled and fuel tanks is 7 : 1.
