Step-by-step explanation:
You start with the top number of each fraction and multiply them. So 2x3=6. Next you take the bottom number and multiply. So 3x4=12. That would give you a fraction of 6/12. 6 is half of 12 so 6/12 simplified is equal to 1/2. Hope this helps!

Answer:
8 days
Step-by-step explanation:
We are told in the question:
Carlos has 4/5 of a tank of fuel in his car. He uses 1/10 of a tank per day.
How many days will his fuel last?
1/10 of fuel = 1 day
4/5 of fuel = x
Cross Multiply
1/10 × x = 4/5 × 1
x = 4/5 / 1/10
x = 4/5 ÷ 1/10
x = 4/5 × 10/1
x = 8 days
His fuel lasts for 8 days
