15/20 To simplify you basically remove the highest common multiple, in this case 5.
(15/5)/(20/5) = 3/4
your answer is 3/4
Answer:
Step-by-step explanation:
1. A car requires 22 litres of petrol to travel a distance of 259.6 km
what is the distance that the car can travel on 63 ltr of petrol
22ltr = 259.6km
63ltr=
cross multiply
{63 x 259.6}/22 = 16354.8/22 = 743.4 km
A car requires 22 litres of petrol to travel a distance of 259.6 km, it would require 63 ltr of petrol to travel 743.4km
2. To travel a distance of 2013.2 km
we would need to calculate the amount of fuel
A car requires 22 litres of petrol to travel a distance of 259.6 km
what amount of fuel would it require to travel 2013.2km
22ltr = 259.6km
xltr = 2013.2km
x is the value of petrol to cover 2013.2km
cross multiply
(2013.2 x 22)/259.6
44290.4/259.6 = 170.610169492≈170.6 ltr
A car requires 22 litres of petrol to travel a distance of 259.6 km, it would require 170.6 ltr of petrol to travel 2013.2km
if 1ltr is $1.99
170.6 ltr is (170.6 x 1.99)/1 = $339.494≈$339.5
The price of fuel consumed for 2013.2 km at 1 liter of petrol at $1.99 is $339.5

Answer is 10:7</h3>
=======================================================
Explanation
It sounds like you want the decimal number to become a whole number. If so, then one way is to multiply both parts by 10 to move that decimal point over one spot to the right
3*10 = 30
2.1*10 = 21
The ratio 3:2.1 is equivalent to 30:21
-----
Then notice how 30 and 21 have the greatest common factor 3. Divide both parts by 3 so we can fully reduce this ratio
30/3 = 10
21/3 = 7
The ratio 30:21 simplifies fully to 10:7
The numbers 10 and 7 do not have any factors in common, other than 1, so we cannot reduce 10:7 any further.
