Answer:
142.24cm
Step-by-step explanation:
If 100 inches = 254cm then if you do 254/100 you will get how many cm are in an inch. 254/100 = 2.54
This means there are 2.54 cm in an inch. Multiply 2.54cm by 56 inches and you get how many cm are in 56 inches which is 142.24cm. This means Elena is 142.24 cm tall.
(a) 32 orange marbles
the ratio of red : blue = 18 : 48 = 3 : 8 ( in simplest form )
