If 4/5 litter of gas runs 12Km how long will 20 litter of gas run?

300 Kilo-meters

Step-by-step explanation:

Since 4 / 5 of a liter runs for 12 kilo-meters and you need to find how much 20 liters would run, you need to find how much a liter can run for.

L is the variable for which how much a liter can run for. Which is what we need to solve.

4 / 5 x L =  12

To isolate L, you need to multiply both sides by 5/4 since multiplying a number by its reciprocal produces one. Note: A reciprocal is a number where the denominator and numerator are switched. Example: 2/3 and 3/2 multiplying it with each other get 6/6 which is 1.

4 / 5 x 5 / 4 x L = 12 x 5 / 4

L = 12 x 5 / 4

L  = 60/4

L = 15

Now you know that each liter is worth 15 kilo-meters and you need to find how much 20 liters will run for.

20 x L = Kilo's Ran

20 x 15 = Kilo's Ran

300 = Kilo's Ran

20 Liters will run for 300 Kilo-meters.

I Hope This Helps You :)

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

i would say b) is your answer

sorry if im wrong
