Answer:
His brother
Step-by-step explanation:
3/10 is bigger than 1/4
WHY?
This is why
first we need to find there LCD (Least Common Denominator)
The denominators are 4 and 10
4-4,8,12,16,20,24,28
10-10,20,30
And since they both have 20 their LCD is 20
Then we need to find out, how many 10's are in 20 and how many 4's are in 20 so,
20÷4=5
20÷10=2
Then multiply this from their numerators so,
5×1=5
3×2=6
3/10=6/20
1/4=5/20
Now we can easily compare the two and since 6 is bigger than 5 that means his brother who ate 3/10 or 6/20 ate more
