77 unicorns, because yesterday the ratio was 6:5 and today it is 3:4. If you add the numbers for both ratios together, you get 11 and 7. Finding the LCM of these two gives 77 (because 7 and 11 are both prime).
You find the LCM of the sums because when you find values based on ratios, you divide value by the sum of the ratio.
e.g. I have 100 fruits. The ratio of apples to oranges is 2:3. How many apples are there?
To solve this you'd add 2 and 3 (5), divide 100 by 5 (20), multiply that by 2 (40) because that's the ratio of apples to oranges.
In this case, you do the reverse. So If I have 77 unicorns, then yesterday there were (77/11 = 7, 7*6= 42, 7*5= 35) 42 green unicorns and 35 yellow. The sum of 42 and 35 is 77. If you do this process with the other ratio you'll get similar results as well.
What kind of spare essay though??
like what does it have to include?

In math, prime factorization is defined as the <span>finding of the </span>prime<span> numbers that multiply together to make a particular number. A prime number is a number that is only divisible by itself and one. In this case, the correct prime factorization of 28/98 is </span><span>(2x2x7)/(2x7x7), and when you reduce the fraction to its lowest term, you will get 2/7. Hope this answer helps.</span>
Ratio of number of orange picks to number of green picks is 2:5.
2+5=7
7 units= 21
1 unit= 3
2 units= 6
Ans: 6 picks are orange.
