I think the word you're looking for is congruent. Congruent angles always have the same angles.
So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
Fiona is not very smart so should know herself what frequency table she should use for her histogram
40% water 60% milk
reason:
if you make then go to 100 by multiplying 2:3 by 2 you get 4:6 and then add a 0 at the end and there’s your answer
When dividing same numbers with different exponents (they’re both 10 so this works different than if they were different numbers) you subtract the top exponent by the bottom exponent. So 15-4=11 ultimately making the solution 10^11. Hope this helps :)
