Answer:
mean but im guessing as well
Step-by-step explanation:
Try 147? it may be wrong but i though that with that type of thing the middle one is supposed to equal double the bottom.
Answer: It should be 11
Step-by-step explanation:
11 + 3 = 14 14 is three more than 11 and when you add 5 you get 19
Lets check...
42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
