what's the question? you only put a formula
Answer: 408/x
Step-by-step explanation:
Total number of people = 816
after 1 song = 816/2 people remained
after 2 songs = 816/4 people remained
after 3 songs = 816/8 people remained
after x songs = 816/x*2 people remained
People that remained = 816/2x
where x is the number of songs
Simplified = 408/x
Answer:
1500 grams of grain
Step-by-step explanation:
How many grams of grain will there be in 2.4 kg of shelled hazelnuts?
Step 1
Convert kg to g
1 kg = 1000g
2.4 g = x
Cross Multiply
x = 2.4 × 1000g = 2400g
Step 2
An 800 gram sample of shelled hazelnuts has 500 grams of grain.
Hence,
800g hazelnuts = 500 gram of grain
2400g hazelnuts = x
Cross Multiply
800x = 2400g × 500g
x = 2400g × 500g/800
x = 1500 grams of grain
