We know that 1 cm = 400 km
Therefore, 22 cm = x
Cross multiply:
(1)x = (400×22)
x = 8800
Answer:
A
Step-by-step explanation:
You first want to simplify the proportions:
7:11 becomes 1:11/7
16:25 becomes 1:25/16
Now you find the LCM of the denominators of the copper which is 112 and that gets us to:
176/112 and 175/112
you see the numerator of the first one is bigger so the number is bigger so the awnser is A
Try 3 because 3 times 3 is. 9
If the dinner is 43 then 18% of 43 is 7.74 so the total is 50.74... If that's what you meant.
